This one started off better than the first but quickly resorted to boring overused plot devices, one-liners, and lazy sequences. I'll quickly run through the flaws of this sequel - and don't ask me why I watched it, I was curious, OK! There's a destiny prophecy, a tree that is the barrier but isn't protected by it?, another very arrogant girl, the same nonthreatening villain, a climax that's easier and worse than other battles, a complete lacking of the titular "sea of monsters" in the film, and another wholesome ignorance of the crucial question: why are the gods and goddesses so promiscuous? This along with a host of conveniences. But there still are some visually entertaining fight sequences and some genuine moments of character development. Uma Thurman was actually kind of good, in a modern stripped down version of her character. Really this one doesn't live up to its potential as the first one didn't. The stakes may seem higher but they aren't and I doubt the ending will ever be fulfilled. Watch it if, I really don't know when you'd watch this. If you're curious, like I was, and to make a somewhat entertaining study of it.
