Here's where things really fall short when they shouldn't have. Being a sequel, one would expect
Spider-Man 2 to breathe some life into a too-straightforward concept. Rather than have players jamming on one button to hit enemies with random punches/kicks until they die, why not introduce custom combos or at least one or two special attacks? Sure, Spidey can shoot web at his foes and he performs a jump-kick when running, but that's about as flashy as it gets. For a multi-talented superhero, this guy can't seem to do much in a scrap.
Perhaps the most troublesome issue lies in controlling Spider-Man when crawling along walls & ceilings. Getting him around corners is a breeze, yet it's almost always cumbersome to dismount from a horizontal site or switch to a parallel surface on the first try. These techniques are crucial when you're trying to drop down behind a gun-toting hooligan or maneuver around detection lights, but most of the time it just doesn't seem to work correctly.
Looking past some glaring faults, Spider-Man 2: The Sinister Six isn't a terrible game... just more of a quick time-passer than a platformer worth keeping. There's plenty of untouched potential waiting to be tapped here, though; with any luck, Spidey fans will have something to look forward to when Spider-Man: Mysterio's Menace comes out on Game Boy Advance later this year.
