I agree with that. But when you get older and see stuff you thought was just the greatest thing ever you see all the flaws and laugh at it but still like for what it is. The issue I see is this:
someone discusses (retro series #90012) due to various factors such as: Remake, Re-imagining Live action movie etc. Fan "X" says it god awful crap and doesn't compare to the original. Other fans say It could have been better but it was still great, At least we got something, Omg I loved it and so on and so forth.
X then proceeds to bash everyone's opinions calling them idiots. Saying the orignial is better because it's from the 70,80,90's . Which then leads to a pointless argument where one person argues the same point over and over again.
Well you get the picture.
So in short its an age, ego and memory thing.
