Why was Tenacious D disliked by Critics?

I have it in my Top 40 movies ever, I think its an awesome movie.

The Tenacious movie, I mean.

Don't know about critics, but personally I'm not a big fan of what I call "stupid comedy" movies, which rely on their characters being idiots to be funny. Zoolander, Tenacious D, Dumb and Dumber, Step Brothers, Ron Burgundy... I just don't find them very funny so I mostly avoid them. The only reason I watched Tenacious D was because I was impressed by Jack Black's passion for music. I still don't like the movie, but I'm glad I saw it just for that final battle against the devil - that was a kickass song.

Agreed on the song part.
