Issue with the accidents
Pretty good movie I must admit, though the overall structuring of the accidents wasn't exactly the greatest.
*************** SPOILERS BELOW **************
For example, you've got the following events:
1) where the guy thinks he's hit someone with his car while under the influence at exactly 11:14.
2) where the father drops the corpse over the bridge at exactly 11:14.
3) where the kids are involved in a hit and run with their van at exactly 11:14.
Only the first two stories above are mutually exclusive. The 3rd one takes place in complete isolation - ie. it neither contributes to the first two events nor is it directly precipitated by them. It intersects only through mere co-incidence rather than logical storytelling.
Other than that, cool flick. "Go" & "Pulp Fiction" did it MUCH better but still pretty good fun!
