Have you paid your dues Jack?Let's put it this way. I've seen back to the future twice and that's enough forever, but I'll watch Big trouble in Little China at least once a year until I'm dead!!!
Back to the Future via not having some scary creepy old evil guy in it.
Honestly I think both of them cover a lot of ground, one of the great strengths of Back to the Future is it manages to have quite separate plots with Marty/Doc plus Marty and his dad. Not actually a great deal of overlap between the two of them but the film doesnt feel unbalanced.Big Trouble is hilarious but it has so much random shit thrown in and the plot is all over the place. That's honestly what makes it great but cant put it over the more coherently told story in Back to the Future.
