In regards to the latter though, it does have a few humorous and exciting parts so it wasn't quite as glaring as the characters and story problems and to be fair to those two problems the original suffered from the same problems exactly. The characters are rather shallow(the twins especially, they are offensive too), the story is formulaic with some of the scenes with the humans on the dull side, the Autobots get nowhere near enough screen-time and some of the script is weak going overboard with some lowbrow and immature humour. Does this mean it is completely flawless? No. And is it the worst movie of all time as I have seen in some reviews and various message boards? For me, not even close. Transformers 2:Revenge of the Fallen is not the best of the year, but it is a long way from the worst either(not like The Ugly Truth or Dragonball Evolution).
And yes, this is coming from a fan of the 1984 series and 1986 movie. Neither of the Transformers films are masterpieces, but neither are terrible movies either in my opinion. I quite liked the first Transformers and this film.
