There must be people who enjoy this film, after all, read the IMDB reviews. However, all the ones I remember reading were by people who read the books and either loved the film for its similarities and portrayal of whatever, or hated the film because it was different from the book.
I watched the first three Harry Potter films (in my early twenties, I'm now 30) before I really tried to read any of the books. The films stand up on their own without the film plot needing to be propped up by the book(s) to make any sense. I don't regard the films as any great work of film-making, but at least the acting is good enough (though Daniel Radcliffe's portrayal of Harry is shaky at times) and the plot makes sense.
In the Percy Jackson movie, there are plot holes so huge that Gimli and Legolas could go exploring in them together and not come out for days. For example:
To anyone who has seen a fair few Hollywood films and knows the standard formula, you'll see where this film is going, and cringe at the cliches.
There are no strong acting performances in the movie whatsoever. Even the key scenes in the movie are below average performances.
