Transformers 3: Dark of the Moon Movie Review

This is the supposed 'end' of the Transformers franchise but I really doubt and hope not. Frankly the critics were actually right this time, it wasn't that good. I would rather the franchise end on a high note than ending on, well, the Dark of the Moon. The storyline was about how the humans had discovered an alien space ship on the moon. It was an autobot ship with important technology which could have turned the tide in the war against the decepticons. The captain of the ship, Sentinel Prime, was in 'sleep' mode. Only Optimus Prime could revive him, which he did. But it turns out that Sentinel Prime was in cahoots with the decepticons and had planned to betray Optimus. He had brought in a lot of Decepticon forces with the technology, which was essentially a teleporter, to eradicate the Autobots. His ultimate plan was to bring Cybertron closer to Earth so that the humans would help to rebuild it. He was obviously foiled through a combination of Megatron betraying him and Optimus Prime delivering the final blow. It may seem like a fairly simple storyline reading this but it wasn't so. The movie made a terrible job of explaining the plot and the fighting scenes were far and few in between. This was actually the only upside as they were really cool and realistic. What had confused me was how the transformers had spilled blood when they were killed. Weren't they robots?
