The following comment includes a piece of the plot. If you plan to see the movie (and I recommend you do), do not read the rest of this.
Both Gene and Roger felt that the title character seemed stupid in that he didn't understand what had happened (i.e. that he went back in time) until the very end. I, on the other hand found it most believable. If you were lost in the desert, and you came across a _rural_ town, wouldn't it take quite a lot before you'd reach the conclusion "Oh, I must have gone back in time!"
