OK, so you want to start out with
HunterXHunter
it's pretty amazing and it's still airing but has 79 episodes so far.
Then move to SAO (sword art online).
Then move to Attack on Titan.
These are my top three animes right now.
If you want to watch something semi-creepy/sadistic watch Code Breaker.
And on top of all this.. if you like Inception/Prestige/Movies that make you think.
Then watch Code Geass.
