I am terrible at watching movies over and over again. I think I have probably seen all 3 original Star Wars films at least 100 times. I can also watch the classics over and over, and still enjoy them.
The Wizard Of Oz.
Sound Of Music
Chitty Chitty Bang Bang
Willy Wonka and The Chocolate Factory
All the Scary Movies
Young Frankenstein And most Mel Brooks films.
Murder by Death
The Nutty Professer. (Eddie Murphy)
The Naked Gun Series
All Star Wars films
Harry Potter...(But not all of them)
Aliens 1 and 2
Billy's Hollywood Screen Kiss
In and Out
There are probably a lot more, but those are the one I can think of right now. I have watched hundreds of movies. The only ones I don't like are slasher flicks, and most of the lastest smash and kill movies. Can't stand them.
