I can't say that I actually enjoyed this movie. Although there were a lot of funny scenes and dialog but the acting is just not good kinda kills it.

Probably because those are new and young actor, I assume?

Everything work way way too linear and not to mention that some of the scene kinda rush IMO. (mind you, I never read the novel)

Most of the fighting scene are not that good and not well-choreograph IMO. Especially Medusa, she got kick out of the bucket too easily. Even Minatour fight was slightly better than that. The series would be a lot better if there are more "magic" attack involved. Percy should use his water spell more often as well.

As for the Casino scene, I am don't like it although I know the purpose of that scene for. I guess it was a the work of "final villain" to delay and waste the heroes time? It is never explained in the end...or is it?

As for the ending, It was alright. Everything wrapped and complete but somehow lacking for me although the credit ending definitely do the justice.

Overall, It is 6/10 for me. Probably because I have extremely high expectation on it.
