*cough*Ahem*cough*
I'm going to go through this and show you how easy it is to counter this lameness:
1) Will's Craft: Metaphor for how her powers were growing; as was her love for Tara. Season six? It's showed how love can lead to the wacky. Season seven? Obviously shown as how even if you lose something (or someone) important to you, it will leave a void, and that void is always filled with something. Or you can look at it like this: Tara's death didn't kill Willow. It made her stronger.
2) Different races: I'm pulling this out of the ass end of nowhere, but look at Rona and Satsu. They've been alive and kicking and playing a main role for how long now?
3) Good and Evil: The world is morally gray, unlike how Charmed is portrayed. There really ISN'T a good or an evil, just a belief of what is right and wrong.
4) Death: WHAT. THE. F--K. Shannen Doherty didn't HAVE to die -- she quit. Like a big quitter. Quitness, aisle one! Death is VERY real in the Buffyverse, it's dealt with on every level that I can think of. Joyce had a whole damn episode dedicated in her memory. Tara shall ALWAYS be remembered by us, and Buffy was grieved off screen and on. (Also, on Charmed, NONE of the main characters have died. You can't be brought back to life by a Whitelighter if you're dead -- you have to be VERY close.)
5) Characters Having Lives: Charmed is a very *light* show, and portrays demons and their bad guys as not a huge problem. A potion and a spell and WOOMPH!, the demon's gone. Buffy had season long arcs and had to follow clues on how to stop something. She didn't have a Book of Shadows to refer to. (Which, by the way, is incosistent. Why would there be demons STILL living that are inside a book that tells how to kill them? Don't you think if the CO's ancestors knew how to kill them they would have taken care of it?) Meanwhile, it's impossible for Buffy to have a life. She's THE Slayer -- the ONLY one. (Well, not really. But Faith was in jail and Kendra died and stuff...) Evil PURPOSEFULLY comes a knockin' directly at her. She's a liability to herself and those around her...
6) "Innocents": Again, the liability thing. Buffy can't and shouldn't get close to anyone that doesn't know how to handle themselves. And it's unrealistic to become "buddy buddy" with a victim on the streets that you just saved the life of.
7) Relationships: Phole failed. Bad idea to begin with. (To be honest I can't stand the Belthazor storyline...) Piper and Leo got married...it WAS boring near the end. It was always the same story...Piper never treated him like her husband. Just someone to scream out to if someone was realistically dead, but then brought back to life. And then she lost him and got him back...and the marriage counseling? That conflict was pulled out of the writer's asses. It wasn't an arc (which admittedly it should have been) -- it was an episode. A quick idea...
8) Morality Counts: The Buffyverse HAS no moral compass, as I've stated before. Well, it does, but everything is still very gray in the Buffyverse. And Buffy had an excuse to act the way she did. Spike was the only person she felt she could get close to at the time. Pheobe thought Cole was "hot" and they went out.
9) Character Consistency: Phoebe was very untrue to herself, to be honest. The way the character was written during that period just wasn't "Phoebe." Meanwhile, Willow had a reason. She lost Tara, who'd she'd recently "lost" and had just got back. Yeah, I know it was her choice to absorb the dark magick, but she was VERY hurt inside. She acted like a normal human being, with supernatural amplifications.
10) Big Bads: The Source. 3 times. And this guy's accusing Buffy of using the same formula? Yeah, the formula Buffy uses IS repetitive, but it's never boring. There's always something new and exciting to be seen, whereas Charmed has a plot you can almost always tell the outcome of. Buffy killed Glory. What's next? Sacrificing herself to save her sister and the world. The Charmed Ones killed the Source (3 times). What's next? "Ooh, Piper -- let's go buy shoes!" (3 times...)
11) Marti/Brad Faceoff/The Wish: Giles was the main character in that alternate universe, and it was thus his job to stop Anyanka. And the whole "Accuse Marti of ripping off Star Trek!" is childish. Boohoo... No matter what, Buffy IS and always WILL BE a smarter show than Charmed.
I love Charmed, I really do...BUT THAT GUY PISSED. ME. OFF...
