I know this is the opposite of what you asked, but I'm someone who really wants to play Raiden but can't.
I played a ton of Raiden in MK1 and MK2, and that's Raiden for me. You look at that now and see a goofy dude flying around in his pajamas, ululating a bunch of gibberish, but it doesn't matter; that gibberish is the sound of Mortal Kombat for me. That Raiden felt dark, dangerous, and powerful. And maybe it's only my imagination--you couldn't quite tell in those early days--but I always pictured Raiden as Asian, like his inspiration character from
Big Trouble in Little China.
In contrast, I just don't like modern Raiden aesthetically. He definitely has some cool lightning visuals, his gear is interesting, his skins are mostly nice (except the ones where he looks like a Christmas present--can't stand those), but his face and voice acting kill it for me (just like some people can't go near Sonya because of Ronda, who actually doesn't bother me at all).
Don't get me wrong, I think his voice actor is talented--I love his Joker, I just can't stand his Raiden. "Dark Raiden" feels like an angry old coot yelling at a bunch of kids to get off his lawn. "Light Raiden" feels like a nice-guy dad who put a basket on his head and joined his kids in jumping off the couch doing electric fly impersonations. After seeing the first MK11 release trailer (Raiden vs. Scorpion), I had high hopes this Raiden would recapture the old feeling, but he just doesn't for me. No more ululating, no more feeling dark, dangerous, and powerful--just a wet noodle version of my image of Raiden.
I've tried to pick him up several times, but can't stay interested. Which is really frustrating because he's the only original MK character I'm interested in. I know I could switch to the Lambert skin, and yeah, he's an improvement, but even Lambert (who's god-like in his own right) isn't quite the Raiden I want. Plus he's sounding pretty rough these days.
Anyway, hope this doesn't offend any fans of modern Raiden! Aesthetic taste is purely personal, so no digs intended or implied!
