Time travel and changing events... hmmm.. let me see...
Back to the Future, Timeline, Frequency, Donnie Darko, Terminator, 12 Monkeys, to name but a few.
I cringed with embarrassment at a lot of the lines such as the hideous use of ****bag in the scenes with George; the bit about the new tricks in bed; the whole "i've lost you once" crap; the bit about being there and having done that with the dynamite.. oh I could go on.
It was cliched and horrible.
IMO of course, and is one of the least intelligent films I've seen in a long time.
