RiffTrax: Rollergator
Available on Prime Video, Tubi TV, Amazon Freevee
If you scooped a pile of goo, fed it while sending jolts of electricity through until it demonstrated the most basic signs of life, then handed it a video camera, it is impossible that it would make a worse movie than Rollergator. This feature is a parody and contains the original movie combined with a comedic commentary by Mike, Kevin and Bill from RiffTrax (formerly of MST3K).
