I always mean to watch it, but I never watch FX so I always forget. Lame.
From what I've seen, I think I honestly prefer that serious to Supersize Me. If you measure Supersize Me by intent and action, it really kind of sucked beyond the initial "oh noes t3h chicken nuggets" factor.
I agree Supersize Me was kind of bad but it did open alot of eyes and I think that was more the point than the whole "this is ur body on McDonalds" thing. I actually did become ill after eating a Big Mac one day and it wasnt from bad meat or anything it was from the sheer fat and oil and crap in it it was terrible havent ate one since 06 and wont I stick with the chicken if I go there which isnt often
