I agree with you.
We saw Bruno over the weekend.
I'll catch this one on dvd. Borat was certainly cringe-worthy and I'm sure Bruno might be worse. Those walkouts probably came because they heard it's a funny movie. They were thinking funny like Judd Apatow funny not this.
I won't spend more than a buck to rent this. I'm hearing that some theatres are posting someone outside the door to make sure under-18s don't try to sneak into this movie. They will still try it, though since somehow or another, preteens still see lots of R rated movies.
I haven't seen Borat and don't plan to see Bruno. That kind of humor just isn't for me.
