Well, if you are a rattrap fan you may not like his new body, anyways i like BM a lot, its very dark...jetstrom he add's lot of humor, with his smart ass lines..and the conflicts with megs and primal are just great....
Well as it sounds like you aren't a big fan of Beast Wars you probably won't care much for Beast Machines. Oh and if Rattrap annoyed you in BW, he's 10 times that in BM. I liked some of it but I would only reccommend it if you are like me and just gotta see everything that has to do with Transformers.
