Why does Hollywood like buffoons so much?

Rating: 4/10 (17 January 2010)

One feature of many modern action films that I dislike a lot, specially in Hollywood films, is that they always put a buffoon (or several) in their films (Fortunately there are films like Syriana or Babel). In "Episode I" it war Jar Jar Binx. In the mummy it was John Hannah (And Brendan Fraser sometimes). I have nothing against a bit of humor, but you should know where and when to make use of that humor unless you want to break the drama and the action atmosphere. Specially when you use childish humor.
I found this film to be a really bad one. Very good special effects, very spectacular, and I have to admit it was entertaining, but I would eliminate some of the characters, like Jonathan Carnahan. Sorry if I think that clowns are better for the circus than for action films.
The only really good thing of the film is Rachel Weisz, which is really impressive (And I am not talking about the acting)
