Short version is: I liked it.
Much longer version hidden as a somewhat shorter version: what Bill Whittle said.
Now, I am not saying that anybody who hates this movie is a Godless Commie: shaky-cam bugs some people on a physiological, psychological, and/or cinematographic level. Some of the science is indeed wonky*. You knew by about halfway through the film where our heroes were ending up. All of these are legitimate criticisms. But if you hate the heroes of the film (note: not ‘protagonists’) for who they are, then you probably hate America and I would appreciate it if you moved out like you keep threatening to do every time we elect a Republican President.
My only real complaint was that going to see this one means that it’ll probably be a while before I see Rango. Which is an acceptable consequence to face.
PS: Also: stupid theaters, not cleaning out their HVAC units regularly. Dust always make my allergies act up.
Spoilers beneath fold.
*SPOILER: The belief is that they’re here for our water, a la V: The Original TV Miniseries. As Larry Niven once noted, this is an odd way to get it: given that the invaders had to fly right past Saturn’s rings, which is made up of ice and nobody is shooting at them.
Another SPOILER: remember this movie poster?
Yeah, well, when that actually happened in the film one of the two on that poster ended up a rapidly spreading stain in a pool, and it wasn’t the Marine.
