I know internet people hate mainstream anime, but I've tried watching some niche ones and they've all disappointed me.
Here's my list:
1. Death(o) Note(Noto): simply put a masterpiece. No words to describe its brilliance (apart from one horrible episode).
2. Naruto: Not perfect, but still absolutely superb when it's good. The idea of friendship is strong in this one.
3. Dragon Ball (Z or whatever). Not that good for modern standards but its influence on some many anime that came after it is undeniable. Because of nostalgia it deserves its spot.
4. Sailor Moon: Guilty pleasure, but also a great series in terms of emotion. I think I cried a few times watching it.
5. Attack on Titan: It's hard to explain why it's so good, but it is. It just is. If you haven't watch it, do yourself a favour and spend a day or two watching one of the most exciting series ever made.
6. Bleach: It's great, but not awesome. I really miss it, but there were quite a few storylines that didn't work well and I did find myself being bored while watching most of the fillers.
7. Sword Art Online: Great idea. Not the best anime, but it's worth your time. Why this hasn't been made into a live tv series (similar to hunger games) is beyond me.
8. Fairytail. It ain't perfect, but it's good enough. Fanservice stuff annoy the hell out of me though.
9. Pokemon. Well, it's not fun any more if you're an adult, but it has its moments.
Can't think of a 10th.
