I know in my heart that movies like Rampage should be illegal. If you haven't seen the movie, I don't recommend it but you should go on youtube or Netflix and try to watch the first 30 to 45 minutes of it. Rampage made me want to puke. I can't believe people actually enjoy watching that. I like to watch a good action movie but not movies like Rampage.
While the movie is definitely not for everyone you obviously got caught up in the gore and missed the moral. What you're talking about is censorship. Plain and simple... which ironically is one of the very things the series preaches against. Try watching the trilogy without getting caught up in the psychopath and listen to the message.
