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.
Within You Without You
Love You To
Tomorrow Never Knows
Blue Jay Way
The Continuing Story of Bungalow Bill
