Sure you want to be sitting between these two?
The mere idea of this long awaited "versus" spin-off, hybrid of two massive slasher franchises, coming true made the fans beg for two decades, prior. In an era that allows for bigger and cheaper CG effects, Freddy vs. Jason is a plastic version of its predecessors. The gore fails on a photo-realistic level. The film looks good but it is overly polished and too trendy to match the expected style.
Where most of the sequels from both franchises featured aspiring or emerging actors that struggled with their lines, the cast, here, does the best they can with a script that isn't exactly in tune with either worlds. Historically, Jason's victims should be dumb and weird; Freddy's caricatural and crafty. When packaged as a whole, they come out as nothing but superficial, partying slackers.
Some scares will work on you, some will be feel forced, and some rely on horrendous effects. While the middle part, a somewhat frustrating procedural, makes the annihilation of horror icons sound easy, and while it takes a while for us to care for the characters, the film redeems itself in the last act by turning into mindless but creative action. This is Freddy vs. Jason, not Freddy and Jason.
