I love Frasier but...
They changed the character so much. One episode it implies that Frasier would NEVER go hunting or as if he hated guns. Yet, in Cheers not only did he gladly go with the gang for the fake snipehunt...but he even knew it was fake but had fun anyways.
Frasier acted like everything of his father and average joe was beneath him. Yet, Frasier became just that in Cheers. He was one of the guys. He came in all rich and sophisticated. But he didn't act like he was above everyone to the point every little thing they did was unlike him. He joined in most of the crazy things.
If Frasier of Cheers and the Frasier of Fraiser met, I think while they'd like each other for their common interest, they'd not get along for their difference in personality and ideas of fun.
In another episode of Cheers, Frasier, though suffer doubt in the end, was all for camping in the cold, yet hated it in Cheers.
In Frasier, Frasier acted like he'd never grow facial hair and how it wouldn't look good on him. However, the final season of Cheers had Frasier sporting one. And he looked good to me.
The only thing I accepted that was ridiculous the whole "Dead Scientist Father and being an only child." I get their explanation was technically stupid. But considering how Fraiser was in Frasier, it sounds more believable that the Frasier of Frasier would pull that rather than the Cheers Frasier. Which is why I accepted this.
I swear, the only thing the two Frasiers have in common was that their names were Frasier Crane, they were psychiatrists, and they were both played by Kelsey Grammer. Otherwise, they were different men.
