Yup. Have watched this movie as much or more than any other. As far as comedies and musicals, this is right up there with the GOAT. Tenacious D and the Pick of Destiny
Though not underrated as an overall film. I think The Incredibles doesn't get it's due as a Superhero movie. This is the real Fantastic Four origin film.
I always enjoyed the good sequels that seem directly connected to the original. Everything from the characters, setting, and music to the story gel together. For example Speed 2 does not.
