Movie games can't be very good because you have such a short development cycle, since the game needs to be done in time for it to be released with the movie. Game development times are normally much longer than movie development times, so there is never enough time to make a complete quality game with a new movie.
That said, making a game based on older movies can and has worked ok, such as SW:KOTOR, X-Wing vs. Tie Fighter, and Cronicles of Riddick. Since development time isn't such a big problem, the developers are able to make a game using their normal process, so the success rate is far closer to the statistical average.
