I wasn't aware of the hate towards Red Hulk, but it was really to be expected since lately people hate everything without a reason, they are accustomed to the Hulk of a lifetime, but if you show them something new, something different, even if it is another character, they are going to "hate" it, in reality it is not that they hate it but surely, I clarify SURELY, they are strange because they are people who live based on movies and have never been interested in even looking at the comics or looking for information about the characters.
