10 Most Underrated Horror Movie Sequels EVER

10. Saw II

Leigh Whannell and James Wan's Saw might have been a surprising success, but it's £103 million box office against a $1 million budget meant that the announcement of Saw II just a year later was anything but a shock to see.

Saw II had quadruple the budget of the first film, and really does a good job in scaling everything up. Whilst Saw was mainly set in just one small bathroom, its sequel takes place in a big house with each room housing far bigger Jigsaw trials and traps. Saw was just as much a whodunnit as it was a outright horror film, however Saw II benefits in a lot of ways because audiences know who the killer is now.

And it's undeniable at this point that the franchise lucked out in casting Tobin Bell as the corpse in the first film, because he remains one of horror's most interesting and charismatic characters. Saw II features more Tobin Bell than any other film in the franchise, exploring his backstory, motives and genius by just sitting him down and letting him work his magic.

While the first film will always be remembered as a classic, Saw II deserves recognition for paying homage to its roots, whilst simultaneously making everything feel bigger and more box office.
