This campy adaptation of the DC Comics series has always been the odd title out in Wes Craven's horror filmography. It's all the better for it, since it's one of the few movies from this overrated auteur that I can personally stand.
Craven tries to do this 'veggie-man' horror in a suitable DC Comics style; and with Louis Jourdan as arch-villain 'Arcane', not to mention Adrienne Barbeau (Mrs John Carpenter) as the Thing's object of desire, he's definitely on the right track.
Sure, it's kind of hokey and a bit campy and has some narrative bumbling and pacing issues, but overall it is a genuinely fun diversion-a contemporary man-in-a-rubber-suit creature feature that also happens to boast a decent amount of heart.
Swamp Thing has many dubious qualities, but it clearly isn't a piece of product tested and polished to a blinding gleam, and the world is duller for not letting oddball efforts like this slip into theaters once in a while.
