I liked it. (Just opinions ahead)

I really didn't think it was that bad. I like all the Ernest movies because they're so silly, and because I grew up on them. I didn't know about the last few movies until quite recently. Yeah, it's corny. The moral seemed a bit forced, but I still enjoyed it.

This is one of the weaker movies in the series, but not the weakest one. I think that title belongs to "Ernest Goes to School". That one is basically a live-action cartoon, but still got me to laugh pretty hard once or twice.
