"The Raid 2" is the most violent movie ever made. The exploding heads, slit, gurgling throats and claw-hammer crunches and tears are so excessive as to make the works of Sam Peckinpah, Quentin Taran-tino and torture porn king Eli Roth seem almost quaint in retrospect.

Excessively complicated and excessive in length, it stands in stark contrast to writer-director Gareth Evans' original film, a tight, visceral martial arts thrill ride that had one good cop (Iko Uwais) battling his way out of a mob-controlled apartment complex filled with villains.

"Raid 2" still has Rama, but is more interested in viscera than the visceral, more wrapped up in confusing subplots than stre-amlined simplicity. And it is more about the blood and injuries than about Rama or his latest quest. That's a serious shortcoming.

Our hero is sent deep undercover, into prison where he does two years' time, cozying up to and protecting Uco (Arifin Putra), the pretty-boy son of a mob boss. Once out, Rama is accepted into Uco's dad's gang.

The idea is he'll help ferret out corrupt cops who protect the Japanese Goto gang. Simple enough. But gleaning that from the panoply of characters play-ed by unfamiliar actors while reading subtitles (it's in Indonesian) takes some work.

"Raid 2" is best regarded as a series of epic set pieces, fights that could be labeled and promoted the way prize fights once were.

There's the Slaughter in the Snow. Then, the Punchout in the Prison Yard, where convicts kick, chop and stab as they're writhing in the mud of a torrential rain.

The Butchery in the Bar introduces the skills of an older, shaggy and unkempt hit man (Yayan Ruhian) who must take on all comers once he's outlived his usefulness. Ruhian is the fight choreographer for this picture, and the best things in it are to his credit.

Murder on the Metro involves the petite, hammer-wielding "Hammer Girl" (Julie Estelle), a ballerina when it comes to hammer-blows.

And so on.

The brawls are always crowded, but always broken down to individual combat. None of the villains are clever enough to figure out, "Let's rush him." Rare is the engagement where guns play a big part. Those usually turn up in the car chases where Rama dodges assassins with shotguns and machine guns.

Evans cuts the fights into visually striking blurs of sound and fury. And there are so many fights that he had a lot of practice editing them into coherent, heart-pounding engagements.

But there are too many. And everything between the brawls is dull exposition, older gangsters trying to keep the peace, cops straining to stay a step or two behind the mob and bungling their loose reins on their man inside the mob, and younger gangsters plotting to turn this Indonesian world upside down.

Anthony Burgess' phrase "the old ULTRA-violence" from "A Clockwork Orange" comes to mind at about the 10th gory stabbing, grisly slashing or gruesome stabbing that Evans serves up here. In "Raid 2" the violence is the movie, its excess used to cover for an inept story, thinly-drawn characters and dead stretches.
