Monster drawn out, boring ass shit
Monster is top anime, contender for best anime I've seen so far along with Cowboy Bebop and Legend of the Galactic Heroes. Monster is masterfully crafted story, the best in anime world by far and among the best of its kind (thriller) regardless of the medium. But it is drawn out, because it takes time to build quality suspense. Don't even try Legend of the Galactic Heroes if you can't take slow paced anime. Monster has best story, LoGH has best characters (there's no contest really) and Cowboy Bebop is the most stylish anime out there with greatest soundtrack. Mushishi is fourth best.
There are many types of anime. I like the least your typical shonen battle anime with stupid punchlines and idiotic story. Quality anime are usually long and require patience from viewer. But reward is almost always there.
You know what else has scored way out of its league? Full Metal Alchemist Brotherhood. It's alright anime but step bellow HxH, maybe step above the likes of Tokyo Ghoul. Maybe because I've seen so many anime in that mold, only thing I liked was humour. Story was known from the start, characters typical, ending just as I predicted. Good anime but nowhere near the best as MAL implies. But neither is Steins;Gate, although it is better than FMA:B.
Anime I particularly dig are works of Baccano and Durarara creators. They have that laid back atmosphere and colourful characters, while being devoid of grandiose save the world story. 91 days is supposedly work of the same author.
Out of big anime that aren't crap (Dragon Ball, Naruto etc.) I haven't yet watched Gintama. Rest I've covered by now. Stuff like Code Geass and One Piece I haven't touched yet, but seems to be that's more of the same mold, just worse than HxH, kinda like FMA:B.
