Admittedly, I never watched the series back in the late 80's. I know... shameful... So, I obviously won't be making any comparisons, but nonetheless, as far as movies go, I enjoyed this one.
I expected a stupid, slapstick, cheesy movie that would bore me. Instead, I laughed. A lot. It was funny. Granted some of the humor was a little more than juvenile, but it was really hilarious. I don't usually go for these types of movies, but this one was well worth the two hours.
Lots of cameo appearances, I won't give any spoilers, but there were quite a few stars in this one. Very cute movie. I highly recommend.
