Ok first. Before anyone yells out "I've seen this thread a million times before! Use the search bar!"
1) Fuck you.
2) Next time, if you don't like it. Don't click it.
OKAY!
My question I pose to you is what is your favourite Anime and why. The reason I ask this is because I'm curious as to hidden gems out there an I want to keep an open mind! It's also not only educational for me but for others who have a similar question.
Anime I like:
Code Geass
This show is great IMO. It has great production values, awesome mech-based action sequences, and a great plot. Sure there is a lot of anime that has Anti-Westerner theme but the show itself makes up for that. It has a great twist on alternate realities like what would have happened if Napoleon had been victorious and if the Nuclear bomb had never been invented. The show revolves around this special power known as Geass which allows the main character to mind control other people to do his bidding.
Death Note
This one is kind of a no brainer. It's about a notebook, and when you write someones name in the book they die 40 seconds later. It is fantastically written and has very interesting characters. Just like in Code Geass, you agree with the mission of the main character but not necessarily the means of getting there. In-fact I drew a-lot of similarities between the two anime based on the main character.
Naruto: Shippuuden
Look, I won't lie to you. There are times when Naruto is unbearably boring. Because it is based on Mangas which can often be quite short on material, the translation process often stretches out in a similar way you might see in Dragon Ball Z. It's common for an entire episode to go by without much actually happening other than talking. There also the occasional story arcs where the team must go on a really stupid boring mission. The times when this show shines are when they are sticking to the main plot. Like him or hate him, the Naruto series does have it's moments.
Juuni Kokki
This one is pretty obscure and it has a very cliche anime storyline. A Japanese schoolgirl (what a surprise) falls into another world and tries to survive in an alternate reality which is similar to feudal Japan. What's interesting is this show has a bit of action, politics, love, character development, and doesn't always focus on the one character. Each season focuses on something different which is interesting.
Avatar: The Last Airbender
Look I realize it probably doesn't count as Anime but I still enjoyed it. Good characters, great story, great action, and a fantastic finale. Not just for kids, it actually gets quite epic if you give it a chance.
Samurai 7
Probably not my favourite anime but I still enjoyed it. It's not particularly long, but it does have good characters, some laughs, giant mechs, and an interesting environment that the characters explore.
I would also like to mention that I love shows like 'The Venture Brothers', 'South Park', anything related to Marvel or DC (such as Xmen, Batman, Justice League, etc), Aqua Teen Hunger Force, and much much more.
EDIT: I'll list a few other anime that I forgot about that some of you have reminded me of.
Digimon
I remember watching the original when I was younger before I went to school. From what I remember it was a good show. Although I am a lot older now so it may not be for me anymore.
Neon Genesis: Evangelion
My friend loved this show to death. I remember watching a couple of episodes and the movie. Even though I know it is a well-loved and acclaimed series, for some reason I never got into it. Although I'm not going to say I didn't like it. It just didn't click with me. Not sure why, it's got everything I like after all.
Elfen Lied
I saw one episode of this (the first one) and was a bit confused but intrigued all the same. I actually forgot about it. I think I should give it another chance no?
Gurren Lagann
I've been told good things about this show and that it is incredibly epic as all hell.
Full Metal Alchemist
How could I forget about this one! Watched it all and loved it. Sorry for forgetting it.
