The real problem is, that its a complete matter of taste. The difference is who has good taste and who doesn't.
These would have to be my least favourite Beatles songs. For the majority, I think my taste is relatively good.
I happen to like I Want You (she's so heavy) as well. I don't see what you've got against it. Its just one of those songs that you have to listen to more than once.
