Leprechaun 5: In the Hood.
We've watched all the others in the series (except #6, in which, I believe, Warwick Davis revisits the hood), and we couldn't do it. After watching just over thirty minutes of the movie, it's our considered opinion that Warwick Davis' contract only requires him to appear for approximately seven minutes.
We could have handled downright BAD, but it was BORING. So we watched an episode of The Wire instead.
After we're done with the Leprechaun series (thank God there's only one more), it's my turn to pick: I've decided on the Silent Night, Deadly Night franchise. I'm especially looking forward to the fifth one, which, according to Videohound, involves "vicious stuffed animals". Rad.
