I went and saw it last night. I laughed so hard in parts that I snorted and had to keep covering my mouth. It really is funny throughout.
I was shocked to see a fairly young couple bring in three little boys all around 10 years old. This is an R rated movie for a reason! It has tons of bad language, is very offensive to women and gays all thru the movie and is of course full of senseless violence.
It is NOT for kids! I wouldn't let a teenager under 16 see this without a parent. Those boys in the theater last night didn't get some of the jokes at all and I heard them laughing in other places that most of us groaned uncomfortably. I don't know what the "adults" were thinking by bringing them there, and I wish the theatres had policy that said no way...those kids should not have been allowed in.
I must be getting old!
Gotta say I loved the movie tho!!!!
