Ever wonder why Harry and Hermione can’t just go back in time several times over if they fuck up while trying to save Buckbeak in The Prisoner of Azkaban? Curious as to how The Avengers pulled out a seemingly random victory at the end of the movie? Do the original Star Wars movies piss you off with their lack of time continuity?
Well fear not, for there are LOTS of people who have noticed all these plot holes, although only a few took the time to compile them into the above video.
