Personally, I think Bay ruined what could have been a great film if they spent more time on the characters. Yeah, the robots should have had a bit more screentime, but if its just more scenes of them being shot at and smashing things then it doesn't really matter. I think its dissapointing because at times the film concentrated just on character relationships (whether human or robot) and in those moments the film really picked up, which only made the rest of the moments all the more uninspired. I also found it very hard to enjoy the action scenes on a purely superficial level because of Bay's absolutely wretched directing--i like a lot of his films and his style, but here he framed the action so closely and incoherantly that there was no communication to the audience as to what was actually happening onscreen. The robots also all looked the same--i could always tell who Optimus was because he was distinctly coloured but the robot fighting scenes, which should have been the highlighted spectacle, were just a mess beacuse it was just parts and gears flying around without any sense of what was happening. I STILL don't know how it ended--I mean i watched it but it was just shot so incoherantly that I really have no idea what happened. Bay's style is also very stale--Armageddon and Bad Boys, for example, are shot similarly, but here its just the same old things; the same music, the same sequences, the same shots, the same pomposity, the same overstated emotion; it just feels like Michael Bay on autopilot, almost like someone imitating Bay.
But I'm also glad I saw it. As pure spectacle, the notion of giant fighting robots is cool no matter the context, genre or competance of execution, and as a die hard Transformers fan it was always nice to see the references and to finally after all these years see these guys renedered in live action. I think the sequel will be much better since all the set-up stuff is done now. The original series was more science fiction while this film is more like Fast and the Furious with robots, but I like the way the ending set up a scenario that was more reminiscent of the situation depicted in the original cartoon. I went into this film expecting a dumb action blockbuster but I was secretly hoping that I would find that it was actually much more--unfortunately it was just as i expected. Okay to watch, captivating at moments where characters take center stage and not the explosions, but unfortunate that its not really worth a repeat viewing. 1986's Tranformers The Movie still stands as a million times better than this.
