Do Movie Sequels Measure Up To The Original? [VIDEO]

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 the original, but sometimes the sequels work!

What movie sequels do you like or dislike?
