5. Transformers 2: Revenge Of The Fallen
The Trailer: I would not call Michael Bays Transformers good per se, but the original was not necessarily offensive like the others. The trailer depicted enough sweet Autobot on Decepticon action to sway viewers in to theaters for some old fashioned blockbuster fun. Considerably interesting hype was built around The Fallen too.
Why It Is Terrible: For a 2 hour and 30 some minutes movie about towering mechanical toys of my childhood beating the holy hell out of each other, there sure was an irritating amount of focus on Shia LaBeouf and various other human characters. Furthermore, the toilet humor (think of all the other aspects the money spent on a small Decepticon dry humping Megan Foxs leg could have went towards) and extrinsic racially insensitive humor really was worthless. This is not a Transformers movie; its a piece of garbage.
