Scrappy and kind-hearted, with odd flashes of high camp - even if its universe of patchworked Greek mythological elements still makes little sense.

Precious little about this is particularly memorable, but it's the odd touch of local color that makes these routine acts of derring-do a bit easier to bear.

The kids are charmless, the adults bemused.

A bad adaptation of Riordan's second Percy Jackson book, but a reasonably entertaining film. Lerman feels like he's sleepwalking through the role, though, instead of settling in to make it his own.
