Gatekeepers is about as typical an anime as there ever was: a mostly-female group of high school kids with superpowers, transforming vehicles, and a giant robot defend the world from evil aliens, but are more concerned with fighting each other for the affections of the hapless male leader of the team. There are a few twists to the formula, like the 1960s backdrop, but this story's been done before. It's done well, however, and anime fans will likely find Gatekeepers to be a fun bit of mindless entertainment.

There are lots of great little touches sprinkled throughout this series, but the whole is less than the sum of its parts. The show can't decide if it's an action/comedy or a parody of action/comedies, and has one foot firmly planted in both. Given Gatekeepers' reheated premise it probably should have gone straight for parody; the ridiculously over-the-top moments are easily the series' high-points. Every TV show should begin with the cast shouting the overly-long episode title at the top of their lungs. The million secret ages scattered throughout the school are a nice touch, and the character of “Big Boss”, a regular joe who somehow convinced AEGIS he has superpowers, is hilarious. But things aren't quite kitschy enough, and when the tone gets more serious Gatekeepers becomes just another action anime. The 1969 setting is a largely wasted comedic opportunity; there's really no reason the show couldn't take place in the present day. Where are the Godzilla and Gigantor jokes?

That said, the stories are deftly executed and the characters are well-developed, even if they are largely archetypes. Shun, Ruriko, and Kaoru are your run-of-the-mill anime love-triangle, and Reiko appears to be the long-lost cousin of Excel Saga's Hatchan. But the show finds ample room to humanize its cast in these episodes and still gear things up for the impending series finale. Reiji is revealed to be the Dark Gatekeeper, no surprise since he's standing with the villains in the opening credits, but the subsequent actions he takes are a welcome twist in an otherwise predictable story. Sandwiched between the two episodes detailing his plot is a character-centric installment in which the entire team goes to Shun's house for the New Year. The interpersonal highjinks that ensue are again typical anime material, but it's the kind of stuff that endears the cast to the audience and separates good anime from bad.

Artistically Gatekeepers is pretty solid. Chiemi Chiba is also thoroughly convincing as Shun's 10-year-old sister Saemi.

The disc itself is well produced. The menus are very -friendly and the standard extras include alternate ending sequences and production art, but one wishes there were more episodes on this release. As four and five-episode discs become the industry standard Silent Möbius, but it's hard to recommend shelling out $200 + bucks for such a middle-of-the-road series.

Jaded otaku may find Gatekeepers too derivative to enjoy, but the formula is tried and true, and it works. It is at least worth a rental if you can find it, and if you don't have a representative of the high-school-supernatural-action-romance-comedy genre on your shelf yet it's as good a bet as any.
