The Collection is a supremely disappointing follow-up to its promising predecessor, The Collector. Wherein The Collector offered legitimate scares, had an excellent sense of tension, and was largely well executed, The Collection seemingly makes a parody of that.
The film starts absurd from the first scene, with a comically clichéd set up, and an increasingly absurd plot. The Collector's mechanisms are elaborate yet idiotic. His lair is an abandoned hotel seemingly in the middle of the city, populated with vagrants. The devices he utilizes seem to be a rip-off of the later Saw sequels, but with even less thought. In short, there is no element of realism to be found anywhere in the film in any way, shape, or form.
The actors are mostly bad, left to inhibit characters that are vacant of any substance, in a film devoid of wit, charm, or, especially, intelligence. It's not "so bad it's good", its "so bad its bad".
