I just went to see it. Meh. 6/10.
It's definitely aimed at young teen males. Don't get me wrong, it had some damn funny jokes. But just seemed crude for crudeness sake. I mean, I love a good crude joke as much as anyone, but c'mon. Sometimes it just seemed forced. Agreed that Stan Lee's cameo was the best ever.
Then color me "young teen male". Everyone in my demographic that has seen it LOVED it! We actually went and saw it again Friday night and I haven't done that in a LONG time.
BTW, graduated HS in '77.
