Percy Jackson: Sea of Monsters (2013)

Director Thor Freudenthal (“Diary of a Wimpy Kid”) finds his groove with a succession of flashy 3-D renderings... They’re digitized riffs on the Sarlacc pit from “Star Wars” and the finale of “Raiders of the Lost Ark” — but as with the “Potter” cribbing, when it’s done well, it encourages “Percy” audiences to forgive the derivative chunks and thin emotion.

There are plenty of bad films to get riled up about in the summer. Percy Jackson: Sea of Monsters isn't one of them. This is harmless tween-centric fun.

That first movie was obviously a calculated grab for Harry Potter-type movie success but didn't feel like a rip-off. This one skews younger, to an easier-to-please demographic, closely resembling other fantasies since.

The quest, which takes our heroes to the Sea of Monsters, aka The Bermuda Triangle, is generic in the extreme. The fights/escapes all lack any sense of urgency and peril.

Percy Jackson: Sea Of Monsters continues a tradition of adequacy that could be described as “epic-ish” or “majestic-esque.”
