I say it was easily 5/5. I've seen every CKY video, Jackass episode, Viva La Bam, Wildboyz, you name it, if it involved the CKY crew, I've likely seen it. But Jackass 2 was absolutely, by far, the best thing they've ever done. Parts of it were absolutely revolting, parts were hilarious. The audience applauded a couple times during it, with feats were accomplished. I had a blast seeing it. Highly recommended to anybody who's into that stuff.
And I don't know about where you live, but where I do, they were checking IDs, both at the door and in your seats. A whole bunch of minors who snuck in got kicked out. The audience applauded and cheered as they were being led out, it was hilarious. Death to Minors!
