I watched this last night, and found that I liked it.
Some of the twists were a bit predictable (like that he was dead/dying and that the capsule was not actually real, but something his mind created symbolically. Which, by the way, visually reminded me of a Terry Gilliam set).
Sure the "rules" of their "source code" don't always hold up in their story line, BUT this was first time they successfully completed their experiment, so it seems like there is a lot of room (especially given the subject matter of alternate universes and residual memory) for the scientists to be wrong or need to change their hypothesis.
Wasn't the premise that the lead character was living out the last eight minutes of another man's residual memories, but that he was doing it in an alternate universe? So basically traveling back in time for those 8 minutes, where he could actually change something. Not the same 8 minutes as lived by the real "Sean". It's really a can of worms...It does seem that the real Sean got screwed out of one of his alternate universes by Jake gyllenhaal. smiley: tongue
