The opening shots of the original Star Wars provides us with a typical cinematic example. The camera pans across a sea of stars. You see a spaceship move across the screen. This imparts a frame of reference for the universe of the movie. Then a much larger spaceship (indeed, it doesn't seem like it will end) move across the screen in pursuit of the original. The frame of reference established by the original spaceship is thus immediately revised in light of this new data. Part of this revision is, no doubt, the expectation that the Star Destroyer will probably be dwarfed by something else (and later in the film it is, by the Death Star). This short sequence actually encapsulates a ton of information: the rebels are small and poorly equipped, the empire is large and powerful. The way the ships are framed on screen also underlines the empire's power over the rebels. And so on.
The realization of the scale and size of the empire is a very small example of sensawunda. And most films don't even contain that much (indeed, the really mind expanding things about Star Wars aren't really SF so much as they are mystical, but that's probably another discussion). There are analogs to this concept in other genres, most notably the horror genre, but the emotions are distinct (the emotion evoked in horror as you realize the scope of the conflict is fear, tension or suspense, rather than the awe or wonder of SF).
Christopher Nolan's new film, Inception, is one of the few films in recent years to actually even attempt to impart a sensawunda, and for that alone, it should be applauded. The interesting thing about Inception is that it manages to impart that sensawunda feeling without relying too heavily on precise explanations of the technology involved. Indeed, I don't think the movie would fare too well if judged solely on the basis of realism.
However, despite this lack of precise technological detail, the film does manage to evoke the sensawunda feeling by devising a set of rules and limitations, then playing around within that box to consistently expand possibilities and sometimes even surprise the viewer. The key catalyst for sensawunda here is that all of the various twists and turns in the story are all internally consistent and logical extensions of what has already been established.
I don't want to go into too much detail right now simply because I don't want to spoil the movie, but things do get pretty complicated and Nolan does manage to ratchet up the stakes considerably more than I had initially expected. There are some concepts or details that I must admit that I'm not entirely clear on, but even in those situations I have a gut feeling that everything does fit.
The critical reception seems to be very positive, though there have been a few high profile dissenters, notably David Edelstein and Jim Emerson. Edelstein writes:
Inception is full of brontosaurean effects, like the city that folds over on top of itself, but the tone is so solemn I felt out of line even cracking a smile. It lacks the nimbleness of Spielberg’s Minority Report or the Jungian-carnival bravado of Joseph Ruben’s Dreamscape or the eerily clean lines and stylized black-suited baddies of The Matrix—or, for that matter, the off-kilter intensity of Nolan’s own Insomnia. The attackers in Inception are anonymous, the tone flat and impersonal. Nolan is too literal-minded, too caught up in ticktock logistics, to make a great, untethered dream movie.(emphasis mine) I found that last line the most representative of complaints with the movie. Emerson's main complaint, that the dreams in the movie don't seem to be very dreamlike, is instructive, because from what appears on screen, Nolan is clearly not even attempting to make an "untethered dream movie". I think it's funny that Edelstein also throws out a number of other movies, none of which I like better than Inception. I do really enjoy Minority Report, but I don't think it captures that mind expanding sensawunda feeling anywhere near as well as Inception does. If you have a lot of problems with Inception, I really have a hard time believing that you'd think that Dreamscape was a better movie. There is some similarity in basic premise, but I think "Jungian-carnival bravado" is far too much praise for that film (which is an enjoyable enough movie, but also kinda silly and overblown in the way a lot of 80s movies were). The Matrix is the only film on the list that I think gives Inception a run for its money. Both films are derivative in the extreme, though I got a fresher feeling from Inception than The Matrix. On the other hand, The Matrix clearly outclasses Inception when it comes to action. In any case, I don't think any of those films should preclude anyone from seeing Inception.
Emerson also seems to hate Nolan's visual style, but to my mind, Nolan is much more distinctive as a writer than he is as a director. It's not the visual style of movies like Inception or Nolan's true masterpiece, Memento, that strikes audiences - it's the way Nolan plays with narrative and time that really differentiates him. This is more a function of the writing and editing than anything else, and even Edelstein admits that Nolan "thinks like a mechanical engineer" when it comes to his scripting (and this is a good thing). The editing in Inception is certainly worth praising here. Though perhaps not as extensive or bombastic as the eding in Memento, there's a real challenge here and editor Lee Smith deserves a lot of credit for whatever degree of suspense you feel as the film reaches its climax.
Nolan also seems to do a great job combining various genres and then putting a new twist on them. For instance, Inception contains elements of action films, heist and con movies, and of course, science fiction. Elements from each genre are mixed and matched in a way that hasn't really been done before (at least, not with respect to the layered "ticktock logistics" of the plot). This isn't a straightforward version of any of those genres, nor is it a simple combination.
The performances are all pretty good, though I think the real standout is Tom Hardy (of Bronson fame), who just devours the screen. Longtime Kaedrin friend Sovawanea pointed out one of the refreshing aspects of the film: "I found it rather refreshing that they didn't try to contrive a romance in the middle of the mission between Ellen Page and the rest of the guys." There's another element of the characters that I found really refreshing, but I don't want to say it because it might spoil the movie.
This has been a slow year for movies, but between Inception and The Girl with the Dragon Tattoo, things are at least looking up a bit, and both will most likely find their way onto my top 10 list at the end of the year.
