I'm not sure I'd use the word "exploits"

It seems to me that "exploits" is a tad too positive.

...based on the exploits of real-life serial killer Ed Gein and stars Gunnar Hansen as the axe wielding Leatherface.

All you culturally literate types recognized the flick which has now "topped a poll of the greatest horror films of all time."

We're talking here about the 1974 original of course. "The only thing more terrifying than the opening 50 minutes of The Texas Chain Saw Massacre is the last 30," the magazine [Total Film] said.

Ed Gein was one of those Wisconsin fellers who made bad. There are persistent rumors, which I like to think are exaggerated, of Gein giving home made summer sausage to his neighbors.
