Taking about disaster, nuclear plant deformation is one, natural earthquake is another one, but making a movie with a quality as low as Transformer 2 was as disastrous as anything else.
Michael Bay and Steven Spielberg are trying to correct this with launching the next Transformer. One of the big correction is the dumping of Megan Fox. Pros and cons: perhaps some die hard fans of Fox would abandon the film because of her departure. However perhaps more die hard fans of Transformers would celebrate for this because the average scores of acting ability in this film would surely be pulled up.
The trailers are not as cool as the previous few. Perhaps we have seen it all, so the excitement is gone. Our enjoyment are ruined by our own expectation. The good news is, now it would work the other way round for you as well. Since you have seen them all and set your expectation to the floor, you might enjoy whatever you can get out from this film when they air it on July 11.
