So there are some HUGE plotholes and general oversights when it comes to making sense of the three movies together. I'm not going to highlight the minor ones but some of the major ones. Some of these are truly embarrassing for a professional scriptwriter to have let slip through the net. The allspark gives Frenzy his entire body back but does nothing to repair Bumblee or his voice The allspark revives both Megatron and Jetfire but despite Prime holding a shard at the end of Movie 1, they leave Jazz dead. If Frenzy can regenerate his entire body from allspark energy, why did they have to rebuild Megatron before using the shard? Micheala has a shard with her that revives Jetfire, why did no-one revive Optimus with it? How could Megatron has collaborated either directly or indirectly with human conspirators if he was frozen in Ice since he first came to Earth? How did Sentinel Prime know Megatron was on Earth if he was offline for so long? How did the Matrix survive after being blown-up when Prime destroys the energy harvester? The Fallen's plan to harvest The Sun and destroy Earth in the process directly conflicts with Megatron & Sentinel Prime's plan (many years in the making) to bring Cybertron to earth. The Fallen, Megatron's master, has no knowledge of Sentinel Prime or his space bridge technology Any other major plot holes in there?
