what exactly am i watching here?

Rating: Null/10 (1 September 2003)

this movie just seems like 4 or 5 trailers attached to each other in an extremely non-coherent way..
main plot: why oh why??? no matter how you look at it (as long as its scientifically), the time travelling/portal are simply unrealistic (not because of the theory, but because of the way and the consequences in which they were portrayed).
subplots: 1: why did we need the focus on drew getting fired? 2: what about the chinese girl? 3: what was the "grandma death" section?
i had a few more, but i forgot them....
