Bowfinger was absolutely hillarious!
But I don't know if you could call it underrated. It got outstanding reviews from what I remember and most of my friends probably put it in their top 20 favorite comedies.
For most underrated I'd go with "Death to Smoochy".
Most people I know think that it wasn't that funny, but everytime I see it it kills me!
Death to Smoochy is awesome.
Kung Pow is even better. All hail Master Tang. :rockon:
