The question looks grammatically incorrect. Doesn't it? Not if you are referring to the Central Perk gang.
I have probably watched each and every episode a gazillion times. I still enjoy it. It is such a shame that they don't make them anymore. Even after a long day at work and a horrible commute, one can always kick back, watch a rerun and feel instantaneously better. Sometimes I wish life was a friendzy. Just sit in a coffee house, chat and be genuinely funny.
To answer the question, It is never too much Friends.
