I'm currently looking at HunterxHunter, has been alright so far
Hunter x Hunter is one of the best shows I have ever seen. Trust me; it will get a lot darker and the characters are really complicated. Togashi is a genius in manga writing and the animation itself is top notch.
I would also suggest Full Metal Alchemist Brotherhood(FMAB), Death Note, Code Geass, One Piece and Naruto.
Full Metal Achemist Brotherhood is consistently rater near the top of best anime lists and has a great story, with some of the best villains, fights and animation.
Death Note is an amazing story of wits, mystery, and is only 37 episodes long. I highly recommend it.
Code Geass is similar to death note in terms of the main character being a "villain/anti-hero" but in a totally different setting. This is only 50 episodes I think.
Naruto is about ninjas( but not in the conventional way) and is nostalgic for me since I grew up with it. I really enjoyed everything except the last arc which left me disappointed and disinterested. However, it is full of action, great characters, fights, music and comedy.
One Piece is about pirates( but not in the conventional way) and is up there but has way too many episodes which is not a problem for me but discourages a lot of people. So I would suggest reading the manga if you have a chance. One Piece has great mysteries, characters and comedy.
However, HunterxHunter is the best shounen anime ever IMO. FMAB/ One Piece are really awesome as well.
Oops, didn't read through the thread and not realized that you watched the majority of these. Oh well, hope others will watch these!
