Younger people goes a lot more to the movies, so the average critic will probably be notably older than then average movie audience member.
Critics tend to be negative towards remakes because "this is unnecessary, the original was better". But most in the audience haven't seen the original so it doesn't matter to them.
Critics tend to hate formulaic and derivative movies, but for the audience it is not that bad, they haven't seen the formula enough time to get bored by it. Fans loved The Force Awakens because it was exactly the same formula as the original Star Wars. Critics were less enthusiastic.
Critics tend to value originality more than the average audience. Hollywood have always been formulaic and rehashed old ideas, but they have still been able to make great movies. But the current movies relies on franchises to a larger extent, and the franchises put hard constraints on the amount of originality and character development which can be allowed.
