I don't think there's any real good reason to dislike the Beatles as a whole because they DO have a wide range and some are going to like the long hair hippies more than the mop tops. To hate everything they ever did I think is kind of ridiculous. Yes, they are tame in comparison to almost everything we've come to enjoy but would we have anything to enjoy if it wasn't for them. I think a lot of the fifties acts would have become forgotten relics (even Elvis) if a band like the Beatles hadn't come along to remind us of what came before. I think a lot of bands like the Stones and the Kinks would have had a tougher time in the States if the Beatles hadn't been around having their first round of hit singles paving the way. Different in style, but a big reason a lot of the following groups even got a listen was that they were British and kids were going to listen to anything British thanks to the Beatles. Otherwise, they probably would have got lost in the shuffle just like British acts before the Beatles (like Cliff Richard or somebody of that ilk).
