Whether deliberate B-movie material or not, playing with nostalgia and referencing to the past is a dangerous game to play. While quirky nods to the predecessors of exploitation cinema is welcome, there's a limit to what is acceptable, and Planet Terror noticeably crosses over the line rendering what essentially is an overall joy ride, into frequency of frustration. While Planet Terror isn't aiming to score high in aspects of originality and refinement, the blatant surrender to obsessive emulation of past works is a slight chore to watch.
Nevertheless, it is a romping ride and certainly has a carefree personality that should be admired. Visually it is typically stylistic as expected of such titles, and the story line is well tailored to allow maximum body count and carry the momentum at an acceptable pace.
It's over the top blood, guts, gore, guns, explosions and what not, and while devious fun as it may appear, its cliched and clunky at best, and it certainly isn't the best offered in the niched genre. Mildly enjoyable, and instantly forgettable.
