Is too much of a good thing not so good? You bet.
I actually got a chance to see a movie in the theater today. My wife chose Shrek 3. We were the only people in the theater for most of the movie, so it was nice and quiet. Too bad the novelty has worn off and the writers have run out of funny jokes.
I laughed non-stop through Shrek 2. I think I laughed 2 or 3 times through all of Shrek 3.
Save your money, rent it if you really need to see it.
