Percy Jackson & the Olympians: The Lightning Thief

I am always excited when a book a really enjoyed becames a movie. Rick Riodan's series was a favorite of mine and right now I am listening to the audiobooks in my computes to school. I love seeing them visually on the big screen.

Now I think everyone wants the movie to exactly like the book they fell in love with but that is basically impossible with only 2 hours so you have to go in expecting a good movie and still love the books but again I loved the movie but some things I wish were different.

Likes:
-I really liked the actor who played Percy, Logan Lerman
-I did not picturing Grover busting a move in Las Vegas but I liked it.
-I liked that Percy and Anna Beth already have some chemistry.
-I loved the fiesty Persephone, wife of Hades played by Rosario Dawson

Dislikes:
-The rule that said 'Gods and Goddess could not see their children', in the book it was because they were selfish and did not care.
-There was no mention of Chronos. This might not be a big deal if they do not make the rest of the movies.

Does anyone know if they are going to make more movies from the series?
