Barring a brief sojourn into relatively low-budget film-making with last year's Pain & Gain, Michael Bay has spent a decade working almost exclusively in the sci-fi genre after The Island and four increasingly nauseating Transformers movies. The director's last straight-up actioner came with Bad Boys II, a $130m blockbuster that offers one of the most ludicrously entertaining genre efforts of the 21st Century, culminating in Will Smith and Martin Lawrence launching a full-scale invasion of Cuba. Like almost every Michael Bay movie, Bad Boys II is packed with poor dialogue and crude humor, but the director's visual style serves the wall-to-wall action scenes incredibly well, especially in the movie's brilliant car chase. However, Bay really throws the shackles off when the action relocates to Cuba to deliver a gloriously over-the-top third act. With the titular Bad Boys in pursuit of Johnny Tapia, they enlist the help of both SWAT and the DEA and launch a none-too-subtle assault on foreign soil that includes the spectacular destruction of a huge mansion and the leveling of a shanty town, culminating in the middle of a minefield that results with the villain being shot in the head before being blown in half. Overlong and overblown it may be, but as a prime slice of big dumb fun Bad Boys II's final showdown is one of the most entertaining there is.
