Movie: Let the Right One In (2008)
Swedish director Tomas Alfredson's vampire masterwork Let the Right One In is so universally adored by horror fans that it's undoubtedly strange to see it on a "worst" list of any kind. And, in the end, the film's lone moment of shoddiness is excusable, being that it doesn't ruin Let the Right One In's overall impact in any way.
Still, the sequence where a bunch of freaked-out cats attack their owner, who's been bitten by a vampire, is a definitely low point in angry cat puppetryand computer animation. They would have been better off smearing crushed Alpo bits on the actress' legs and letting real felines have at it.
Also worth ridiculing: The 2010 American remake, Let Me In, an altogether excellent and seriously underrated film that's briefly sullied by some crappy CGI whenever Chloe Grace Moretz's pre-teen vamp attacks people. Blame the cartoonish facial alterations and sudden jumping abilities that make it seem like someone's jamming down on the Fast Forward button.
