Biggest rental regret from back in the day?

[KManX89]

I know movie rentals aren't a thing, anymore (thanks streaming), but they were once upon a time. What movie did you most regret renting from your local Blockbuster, Family Video, etc. back in the day?

Anyway, I was browsing the horror section and saw the cover for The Human Centipede and thought "that sounds interesting". At the time, I didn't know about its "concept" and seriously thought about renting it, but luckily, I decided not to rent it. Instead, I rented Pulse. I figured, it was a free rental with my Rewards program, so what the hell? Biggest waste of time of my life, that movie was atrocious on every level (and boring, which is the worst thing a movie can be). Afterwards, my friend was like "they should've paid ME to watch that shit".
