Adventure movie that would have worked better as a TV or mini-series as the effects and the story line isn't epic enough and the acting seem more suited for a CW show. Especially the cyclops half-god/brother story line isn't particularly interesting. The film also ends with a cliffhanger that will never be resolved due to lack of interest. Nathan Fillion had a fantastic short appearance as Hermes though.
I have to admit: This film soars when it actually has fun. But the rest of it is a problem. Heavy w/ exposition & subpar battles, this sequel chokes out all potential. Honestly, the entire movie should've involved Fillion's Hermes, since his scenes gave the film a breath of fresh air even with a slight Firefly nod.
