There are many of them, but to be far I'm only go there a few of them. Racial Stereotyping is one of the most talk about topic that seems to be brought up in the films. I really don't have big problem with this is a few of the characters in the films, but when it's every single film. It shows that we have to secretly have to make fun at a way each race talks, looks, act & thinks. We to have some better personalty in each of the Transformer, but we get is backlash that know that was coming in the beginning.
Over Sexed Women is another command issued that people that seem to have. I think that the women are too sexy for the kids that I see in theaters. It seems that this just fan services for all the wrong target audience. It just feels weird to me that we still need have Sexy girls to sell a movie that is mostly aimed of kids.
Not Enough Transformer Screen Time seems to the biggest problem that many people seem to think that we don't see the Autobots or Descepticons on the big screen. I like to see a lot of Transformer time on the screen, but no. All we get is a cast of humans that need to be the support character & not the main part of the film. This was been my big problem that I hate to make a major issue, but I think that we all know that this is the biggest problem.
Like I said there are many more, but I'm not going to name them all. I can link a video to this post so you can see more of them. I hope that we can find a way to save the downward trend that the films seem to go now. I hope that we all can live to see more transformers films. With the right touch we can all have a great time with a good film.
