The Transformers first movie is both a favorite and isn't. It is my favorite because when I was young I loved watching the cartoon Transformers G1 series, Armada, Prime, etc.but again they were all cartoon series. Seeing it live action, even if it's not made well and bad, still has a special place for me.
Michael Bay has made a lot of movies including all movies transformers and personally I have respect for him because of that more of because he made the series into live action though with his own twist on it. As a kid that was a dream come true having in some way something coming to life in a way.
Shia LaBeouf is the leading guy and a big part of the first movie. He is the leading male for the first three movies out of the five main and one side movie.
Megan Fox was the leading woman in the series for two movies before there was between Michael Bay and her and left the movies being replaced.
