I know many people came of age with the prequels, and identify with them as their personal Star Wars experience.
My coworker, born in 1990, was recently telling me about how the prequels defined Star Wars for him, while the OT seemed somewhat outdated and campy.
I'm all for walking in others's shoes, seeing things from different perspectives. But hell, I'm sorry, I consider you prequel people a lost generation. A poor, warped, lost generation. May the Force have mercy on your souls.
some people just like visuals better than story/themes/etc...
My gf liked the OT, but she kept saying "the graphics suck", whereas no such comment was made for the prequels. But she is like that with everything (Tv, video games etc..)
But to be fair to your co-worker, some things from the OT are bad.
Something which I find important in the SW universe, lightsaber duels, was far superior in the prequels, in terms of choreography. Keep that 'powerful' bullshit out of this. Old Obi vs Vader, purely as a fight, sucked.

Luke vs Vader (Both times) are good though, they're not just standing still waving their stick at each other.
