8. Swamp Thing

As it was made in 1982, the action comedy movie adaptation of the Swamp Thing lacked the visual effects technology to capture the comics’ supernatural horror feel. However, it was good enough to prompt DC to revive its series, which still continues to this day (a feat for a character with such a name, if you think about it).

Fans would definitely love a Swamp Thing movie with all the gorgeous CGI that’s available today. However, it’ll be tough to oust Groot from the current popular plant-based superhero throne; his cuteness and solid warmth trumps Swamp Thing’s enormous power.
