I just read an advance screening review, and it got some positive responses:

I like the concept, sorta like Apocalypse Now meets The Three Amigos. Stiller's movies may not be Oscar masterpieces, but I'll be damned if I don't laugh a lot.

Found a website for the movie, a bio for Ben Stiller's character, Tugg Speedman.

I love everything about it, the bio, the trailers, the charity ("Pandas. Their survival is not so black and white." lmao!). The R rating and red band trailer already sold me, but the little add-ons like this are making me go opening night.

Hah, I just checked out the sites for the other two main characters:

I got to see a screening on Tuesday night, and this was great, exactly what I was hoping for. All the actors do a fantastic job executing their roles. Personally, I thought Downey was the best though. He was switching from one role to the next at one point and it really impressed me. Some great cameos in this that I don't want to spoil, too. I'd definitely see it again just to be sure I caught all the lines.
