Thank you for explanation Bumblebee.
Yeah, I can understand that and as you said I don't think it's really the fault of creators or writers and such. Even if we put the licensing stuff aside, movies are much more expensive to make and have limited time so you can't really put everything that you want in them. As a fan of MCU, I fully understand that I'm getting the inferior (in regards to depth of characters and storyline) experience with these movies but I still love them for what they are.
I just hope that more people would see these movies as their own things and stopped comparing them to the comics. (which will never happen)
