I like him. Of course I'm not CRAZY about him, but that's probably because I'm not a girl. I don't squeal with delight when Drew flicks his hair or when he hands May roses, or have my eyes glued to the screen when he appears in a bathing suit.
I think one of the most appealing parts of Drew's character is how he's changed since his debut. He originally came off as just an arrogant pretty boy, who just tried to rub his wins and his talent in May's face every chance he got. Drew has changed a lot since then, and the writers have given him some good backstory to make him seem like a more realistic character.
Of course, I also think he's troubled in some way. He keeps most of his thoughts to himself, and he can become quite scary at times when he starts yelling, (see preview to 2nd GF episode). He's also a bit of a loner, only have one real long time friend, and basically having no family that cheers him on.
Its also nice to see his team moving away from his girliness, (what kind of guy prances around with a Roselia as his lead Pokemon?) to more masculine and powerful Pokemon. He's in general a good character because he does what he needs to do, be two steps ahead of May, and increase the shoujo aspect of May's storyline. Its amusing to see those ignorant people on the lesser Pokemon sites try to claim that May's storyline is not shoujo, or that she's not important despite having these rivals and her own quest, what a bunch of elitists. I can't wait till the writers push their faces into the dirt, and those losers will have nothing better to do than try to rationalize the show for the next three years, and how their "precious" Misty is going to wipe clean what the writers have established for the last 4 1/2 years.
Hm, guess I got a little off topic there. In any case, I like Drew, but some of the fangirlism can get a little disturbing.
