That's a false equivalency. 22 Jump Street and Beverly Hills Cop were set up to be comedies from the very beginning, and they advertised their rauchiness. Transformers was not. And Bay explicitly said that DOTM would be more serious, and it turned out to be a flat-out lie on his part. And the "it's just robots fighting" excuse fails as well. Things like Beast Wars or Transformers Prime shows that you can do that, and still tell reasonably mature/serious stories. And they certainly didn't rely on racist/sexist/homophobic/offensive humor. That's all on Bay.
So you're saying that because they, quote on quote didn't show how much humor was going to be in the films at the outset that none of what I said then applies? Sorry it doesn't work that way. And even if it did, that would mean everyone walking into part two would then have been indoctrinated and no longer able to make this 'claim'.
However, like I said, it doesn't work that way, how a studio chooses to sell their films means little when it comes to judging a serious movie as a serious movie a judging an action comedy as just that. These films, with their constant scenes of actors hamming it up are action comedies....period.
As for Bay 'promising' the third film would be 'more serious' I must have missed the quote. I do recall him speaking of what they set out to do relative to the disaster that was the second film(and how that came about..no script) and why this the third one would benefit. He also said several things about trying to capture the magic and human story of the first. Anyone that insists DOTM was the same as ROTF is kidding themselves imo. I'd argue it was more focused than most modern comedies. Lastly, If bay said it would be darker, than he was also right about that, I saw sam doing things in the third film that would quality as darker and 'more serious' than the prior films.
It's only a lie if we go by what you claim he said, and as you say he said it. Which, is clearly false. Bay and the producers have been pretty upfront about what they aim to do with these films. The recent producer interview talks all about it.
"racist/sexist/homophobic/offensive humor" is actually in alot of movies but only called out in bay films. Again 22 jump street....But then again, I suppose that film's marketing excuses all of the above. Secondly, I personally haven't seen any of that in the films, not in any sort of abundance. But that's me.
As for TF prime and Beast Wars and such, last time I checked, neither of which appealed to the same level of audience these films do. There maybe several different reasons as to why but that fact is they don't. That's what is actually 'all on bay'.
The next time someone tells me the comic books are 'better' I will have to ask them how many people buy the comic book(and consistently). I'm imagining it's not 1.3 billion worth in sales(per issue). The content is designed to do generate different returns. Simply appealing to some portion of fanboys isn't what paramount is interested in. That might be what they are into with GI Joe but not here.
^That last part isn't me suggesting things need to be silly or what not to sell. Rather that the two shows you point to simply don't have the burden of performance to this level and scale an audience, thus constantly pointing to them as some example is...mostly pointless cause it doesn't actually prove anything.
