Question: The book covers several generations, so with each generation you have to re-learn all the characters. It is difficult to keep track of who's who when every time you get to know the cast, 200 years suddenly pass and we're in the middle of a new crisis. I didn't read the whole series because of this -- it was obnoxious.

Answer: Negative

Question: The special effects are what you expect from the Transformers series, but the story line also is unfortunately what you expect. It's just more of the same disjumbled events getting thrown together. Some parts of the movie flow well, and others are just plain ridiculous. It's past time the writers & director for this series either move on or grow up and quit turning every scene into some kind of teenage behavioral prank. They've done the bumbling parents, the stuttering idiot Witwicky kid, the jive talking robots, and the goofball super secret ex-agent to death already. How about having grown adults who are fighting for the planet's survival actually act like it?

Answer: Negative

Question: A continuation of the illest hip-hop album in recent times, 400 degreez. If you aren't down w/ C.M.B yet, go get 400 degreez first. If you already got and you love it, this is just another hour of banging bump and car music. Great

Answer:
Positive
