I have to agree with you tho I am a big fan.
I won't go see them live anymore, without Ace and Peter.
While Peter Criss is the most useless drummer of all time (IE - his drumming live is 100% triggered, tho even a 2 year old could notice tihs), Ace was a major part of their live show.
Anyhow, Gene and Paul have both stated that KISS as a brand is bigger than any member, and that it could continue even without Paul or Gene.
