Okay, so most of the film explains how he goes into "source code" to see if he can extrapolate variables that a computer generates based off of real-world events/variables and Fentress' brain.
Someone explain to me - everytime he comes back to "reality" (even the very first time), you see the egg that he ends up at with Christina at the "end" of the movie?
I liked the prequel, Groundhog day
It was meh.
Deja Vu (Tony Scott, Denzel Washington) was better for silly action implausible sci-fi.
