This movie was so awful, I loved it!
I saw this film in the theater when I was in high school and couldn't get enough of the cheesy horror flick, sci-fi, and all that was in-between, and "Swamp Thing" was just the right kind of movie I needed to see at the right time to enjoy it as I did. Adrienne Barbeau had the right assets for a high school boy, and to this day I love any movie or TV show with Ray Wise.
The effects were pretty cool for that time, though not too sophisticated as they really didn't need do be. As long as you had some dry ice, food coloring, water, beakers and such, and a green rubber suit that looked a bit like a walking bean stalk, this was the movie to make following in the tradition of bringing the comics we read and collected to life on the big screen. Sure, I had Swamp Thing comic books (DC) (I guess they're called 'Graphic Novels' now). A few more prosthetics and Wes Craven writing and directing and you have "Swamp Thing" the motion picture.
Rent it, buy it, stream it, just watch it, and grab a bag of popcorn if you love these movies like I do. In other words, just enjoy!
