Its a no brainer realy. You may not enjoy his drumming, because of the style of music you prefer, but to knock the guy or say he was not a good drummer is just trolling.
He is the most famous drummer on the planet, not cos he was popular in the 60s but because his drumming has endured. The guys back then were making up what we now take for granted. Anyone can copy, it takes a real musician to innovate. If you go to colege or a drum teacher to learn to play they are pretty much teaching you what Ringo and the drummers back in the 60s and 70s started or what the Jazz greats from back in the day began.
Its the young drummers job to pick up the batton from the older guys and take drumming a bit further. Thats the way its always been, but dont knock the drummers from the past simply cos you can copy there chops and play them a bit faster.
