Some of my favourite series that if you haven't seen, I suggest you check out.
- Baccano!
- Hokuto no Ken
- Hajime no Ippo
- Last Exile
- AIR
- Clannad + After Story
- Full Metal Alchemist
Would have to say that Baccano! is easily my favourite series of all time. It's only a short 16 episodes, yet it covers more material and character growth than your average 26 to 50 episode long series. The plot is hard to grasp until the end, but that's how it's put together. The characters are extremely captivating, and despite being only 16 episodes long, there's at least a dozen characters that are all equally important to the plot. Music is top notch too, and it's got a great mix of humour, action and drama in it. Art is also absolutely fantastic.
