When I saw this question I went to go look at my collection and the first movie that stood out to me was Uncle Buck. A feel good movie from the 80's starring John Candy. It was funny the way funny was funny back then and it still cracks me up to this day. If you haven't seen it I hope you check it out.
But my all time favorite is the original Teenage Mutant Ninja Turtles movie (1990). I've always owned a copy of it since I was a kid.
