Everything just seems to contradict in these movies, at the start of the first one earth is an "unknown planet" in the opening monologue, then the next thing is during the next few movies its been visited by them more often than a bargain basement whore house, the primes hid the matrix there for part 2, Megatron and Sentinel were supposed to rendezvous there for part 3. Unknown???
And if the plan all along (even predating the first movie) for part 3 was for Megatron and Sentinel to bring Cybertron to earth to have slave labour rebuild it wtf was the point of the plot in the first 2 movies which was to use the allspark to take over the universe, then to destroy the sun in part 2 which would presumably destroy the earth with everyone on it anyway??? .
Bay couldn't even get the names right, Brawl became Devastator in the first movie, then we have a 4 legged vacuum cleaner with testicles masquerading as Devastator in the second one. Barricade vanishes en route to the final fight in the first movie then randomly appears in the third one, talk about a massive continuity error. And we can't forget about the influx of random silver decepticons who all looked virtually identical, you seen one getting killed then you realised there was a ton of them. Instead of making them recognisable decepticons with names they just seemed to be nameless clone grunts.
One thing bay is great at is "bigging up " certain characters only for them to do nothing or barely appear, Shockwave being the prime example for part 3, what did he do exactly besides ride about on a driller bot and get owned in record time by Prime near the end?
Its like they took random scripts containing "ye olde convoluted plots" put some glue on them, threw them at the wall and whatever stuck got made into a movie. I swear there must have been some serious crack being smoked when these things were in the development stages because the plot holes are so big its not even funny, If the plot holes were physical they'd be about the size of the moon ffs.
Just goes to show that a good story isn't necessary these days, over the top cgi and explosions sells and that's all bay is good at.
