October's signature holiday is quite horrific, but is Halloween's terror quite as revolting as the Scum Bucket? Peter Travers breaks down Scumtober and picks the worst films of the spookiest month. Cloud Atlas, The Oranges, Here Comes The Boom, Paranormal Activity 4 and Alex Cross all get shoutouts for the month's most horrible flicks, but what's the biggest dud?

Let's just say it's that film where Liam Neeson's enemies should've learned their lesson the first time – don't take things from him. "The first one, even I liked. It was a great guilty pleasure. Now what happens?," says Travers of Taken 2. "He's just trying to save somebody again. How long is this going to go on?" Apparently, already too long.

Let Travers know which of this month's movies you'd toss into the Scum Bucket in the comments below, on Twitter or via e-mail.
