Oh yeah, to add onto Spirited Away, Birdman and Trainspotting
I've tried to watch The Godfather twice and gave up both times after 20/30 mins. Didn't hook me at all.
Also just remembered Ghostbusters (the original), really didn't like that film at all.
And lastly, Don Jon. I like JGL but written, directed by and starring him, just seemed like an excuse to bang Scarlett Johansen all day tbh... which is fair enough but didn't enjoy the movie.
