Firestarter 2 is an entertaining movie. Although it does not live up to the expectations of Stephen King fans, you must remember that Stephen King had nothing to do with the movie...
Charlie is a grown up now and we should expect her to do grown up things, not just run and cry when life doesn't go her way. The characterization is great. The first part of the movie, she is working in a library and goes to clubs to find male companionship with no strings attatched. What would you expect from someone who has lost everyone she loves and fears loving anyone else for the risk that she may lose them.
