This one is quite a strange and humorous take on the Texas Chainsaw series. Even the movie's poster cover itself is a mockup of The Breakfast Club (1985). It's the black sheep of the bunch, and it's the first we get to see a soft side of Leatherface, while only being the second film, and Dennis Hopper is a hero in this one!
I definitely recommend the Scream Factory release which includes a ton of unrated material that was cut from the final. Happy 30 years!
