I just don't understand how the same director could have made The Source Code. The trailer, at least, makes this look like a run-of-the-mill thriller with your regulation number of explosions and desperate embraces in the face of disaster, with a dash of mind-bending sci-fi thrown in to differentiate it from other run-of-the-mill thrillers. It seems to be getting good reviews (91 on Rotten Tomatoes, 75 on Metacritic), so maybe this is a case of misrepresentative trailers.
It is important to note that Jones did co-write Moon, and that it was an independent film that went through Sundance, SXSW, and the Tribeca film festivals. Source Code, on the other hand, smacks of big studio. The two movies don't share any cast or crew beyond Jones.
Maybe it's actually good. Maybe I'll actually see it. But it's not looking so good at the moment.
