Here's a couple of more:
KISS has some fun songs and they get hated too much. They're far from the greatest band ever, but they have a few cool songs in a turn off your brain way. It's dumb fun like fast food for your ears.
Never got the complaint of "all AC/DC songs sound the same". What do you want, a deep political song? Jazz odyssey?
There seems to be a big backlash towards classic rock in general. If it's not your thing, that's cool, but why hate it? Seems like part of it is because it's old and the boomer generation likes it. Over exposure is one thing, but that doesn't mean the music sucks.
