I can't think of one movie from The Rock that I really liked except for The Rundown. Everything else has been a huge disappointment. I agree, that has nothing to do with his size and everything to do with not picking the right parts or good movies to act in.
As far as kids today, they will be primping collar popping weaklings who think anyone close to 200lbs is on steroids and insane for getting that big. They will run from creatine and when they hit their 40's and 50's and experience a drop in testosterone levels, Congress should have convinced them all by then that HRT is evil, criminal and that they should just let their sex drives and bodies fall apart because bodybuilding is bad, mmm'kay.
