I loved the sea of monsters because this movie is packed with action. I say this because the lord of the titans starts rebuilding himself after his son Zeus and his brothers chopped up their father. Kronos became very angry and vowed that when he will be reattached he will unleash chaos on the gods and the mortal world. The part which i thought was not very realistic(what i mean by realistic is that the monsters able to hear everything properly since they are monsters) is when the cyclopes friend of Percy(One of the heroes) gets all sorts of noisy things in his bag and infiltrate the ship where Luke is the bag of the cyclopes makes a lot of noise and the monster at that exact moment should have seen Percy, Annabeth and the cyclopes(Tyson) going up the stairs. This part could have been a bit more action packed like the monster calling reinforcements and fighting with the Demigods and The cyclops Tyson but they didn't. This was the only part i thought could have been fixed a bit more. Other than that the movie was pretty good.
