The anime recommendations HAVE to be in one of these three catagories; Action/Adventure, Comedy, Sports.
Awwwww, as a pretty big Horror/Mystery anime fan that really breaks my heart and limits to what I can recommend; however I have seen dozens of various animes of all genres too. It's just horror/mystery is my favorite type. In any case, I would recommend these ones:
Working!!
Working!! can be pretty hilarious but I suppose it depends on your exact type of humor. It currently has three seasons, each 12/13 eps.
Parasyte -the Maxim-
Are strange, murderous aliens/parasites your thing? Give this a try! Each episode only got better and better in my opinion and it does have quite a bit of actiony, intense fight scenes despite not really being classified as Action. Definitely highly recommended in my books.
Mitsudomoe
This is one that caters to a specific type of humor, mainly the huge misunderstandings/cringey and perverted kind. It has two seasons, the first being 12 eps long while the second is only 8 eps long. I remember watching it years ago and laughing/cringing a lot.
Pani Poni Dash!
Cutesy, very random, and has tons of various references to many things left and right. Not to mention it enjoys breaking the fourth wall quite often in subtle ways. I love this one and would gladly watch it countless times; however I've only watched the dubbed version.
Katanagatari
Firstly, I absolutely loved the art style in this one quite a lot. It's action, comedy, and drama and each episode is actually an hour long and I believe it had a total of 12 episodes. I really enjoyed this one and still can't get over how nice the art style was. A good, personal favorite.
Kara no Kyoukai
This is actually an anime movie series, and I loved it; however I should warn you the movies were not released in chronological order so they may confuse you unless you want to look up what order you should watch them in. This one has some drama, horror, and lots of action. I do admit that one or two of their movies were quite boring though but they had some pretty amazing ones too.
The 5th one, "Paradox Spiral" was my favorite out of the bunch. The movies range from an hour to two hours, and there's 9 total I believe.
Lastly, I will take ALL Advice so plz give me some. A friend told me about how I should not watch just one episode when I try them (I'm confused what he meant).
It's because there's quite a few animes that takes a few episodes before they actually get good or can hook you. Some animes just start off slow and seem uninteresting at first, and some escalate very quickly. Always try to watch two or three episodes (or more, depending on how long the anime is) before deciding you don't like it. It can be quite easy to dismiss something before giving it a chance.
I even have this flaw because I tend to rely on summaries/descriptions a lot before even attempting to watch them, and boy I've missed out on quite a few good ones that way that I wish I got into a lot sooner because of that way of thinking. I'm still trying to break that habit.
