movie sequels

I was watching "Back to the Future" this past weekend and I was telling my wife that I like three movies in that series of movies! I also like all the "Naked Gun" movies, "Grumpy Old Men" and "Grumpier Old Men,"  "Home Alone" & "Home Alone 2 Lost In New York" didn't care much for part three of that series. But anyway it's hard to top
