Bay is at his best in directing the 1st movie in terms of thrilling action sequences, and the story are decent too.but since Ehren Kruger join start from 2nd movie, the storyline just drop to bottom..The action in the beginning and the half of ROTFstill great but just a mess in the end..The theory and action style all turn to lousiness... What I meant here is come on, there are Transformers, so many weaponry and function they can use, why just like human fighting and use weaponry like machine gun only??For example they can use laser, sonic wave, rail gun, powerful alien missile, invisible protecting shield etc, and weapon that not in this world like in district 9..there are so many choices you know.. as we can imagine.. Second is the way they fight, please don't fight like human, maybe Michael Bay just run out out idea since Tf1, they are Transformers, be more creative of using weaponry during battle please..And bring more transformations on each robots. 3rd is the most stupid stuff, Decepticons to drive alien jet?please..they are Transformers, just bring in Aerial Decepticons would be lot watchable!Those unknown protoform robots and alien ship are very unnecessary you know..all we need is around 6- 10 real decepticons that got character name n more screen time on them, just don't easily kill them with a shot or punch, that's really sucks to watch if die that fast..and military are impossible to kill them in easy way.. As for Transformers design, what the hell is Michael Bay want more like human face n body? Please.. there are robots, don't make them look like us, got beard, fat and old?and red blood?just wasted the robot character development especially Jet Fire, he suppose to look like Robotech.And Devastator, he need to be cool, not like a slow motion gorilla please, just strange why Michael Bay will accept the art work for that.And the combiner should combine when each of the Contructicons can't defeat autobots, not straightaway combine to Devastator, this is a big mistake. I just hope that they can find a right director that know how to fixed all these, and if Paramount can choose someone to do it..I think James Cameron & Guilermo Deltoro would be the best but seems it's impossible because they got many project in hand..Anyway sorry for my broken English here...I just wanna share what the weakness in Transformers 2- 4...I just wanna voice out what I dislike about Transformers Trilogy that are keep disappointing me start from the 2nd movie.And with TFCU, I hope they can have an Autobots team spin-off like Aerial Bots and Protectobots.
