3.5.
The second X-Men film novelization is much better than the first. Handing the reins to longtime X-Men writer Chris Claremont was a smart move, as he knows these characters inside and out, and writes them with such a comfortable ease that it's hard not to get involved in it. Surprisingly, this is actually a decently written book, especially for a movie novelization, most of which are pretty artistically worthless. But Claremont shows a keen eye for detail in not only getting into the environments and sensations of the world, but also the individual character's heads, their thoughts and feelings, even going so far as to offer bits of development for background characters like George McKenna and Alicia Vargas. Overall, this was much more fun to read than the first book, and went into much more plot and character detail, making it able to stand on its own two feet rather than seeming like a dry relation of the events of the movie. In fact, one of the most interesting things about this book is what's not in the film version, such as cameos from Gambit and Beast, and a radically altered ending. It's not perfect, there's quite a few unnecessary adverbs and the occasional clunky line, but compared to the first book, this was really fun, and served as a proper extension to the film version, rather than feeling like a cheap tie in. Recommended for X-Men fans.
