Help me decide what to watch next from my watchlist

You have to watch GTO (1998), it's a masterpiece.
Trust me!

Jimi ni Sugoi

Kazoku  Game.

Whoa you have a lot. Out of all on your list the only one that I watched was Beautiful Life. I think it’s worth watching 

1 Litre no Namida Special is a great one, if you want to feel sad.
I had to drop Akumu-Chan , if that helps at all.
BACK STREET GIRLS - Gokudoruzu  is hilarious!!  Recommend!
Koizora was a great movie, though, also sad.  Recommend!!
Ossan's Love I went ahead and linked you to the special, which I LOVED.  Haven't finished the actual series yet, because it didn't start off good for me.  Recommend!!
Ouran High School Host Club This show is so stupid and funny, very much following the anime, it's super cute.
River's Edge I loved the cast in this, mainly the ML, but really, it's just a dark, disturbing, weird movie.
Tokyo Vampire Hotel This series was pretty awesome.   It sort of came out of nowhere for me, and it's directed by one of my all time favorite directors, Sono Sion, so I was pretty easy going with it.  I can see how people can be critical of it, though, but to me, it was just a really fun watch.  It's free on Amazon Prime!

Bara no Nai Hanaya.  Interesting, because it contains a little bit of everything:  suspense, family life, and, of course, romance.   Definitely worth the watch.

-Buzzer Beat (romance.  watch even if u dont like basketball...)
-Love Shuffle (psychological)
-L♥DK (cute, and actually being remade)
-Nigeru wa Haji da ga Yaku ni Tatsu (well done.  Precursor to Because this is my first life (KR))
-Nobunaga Concerto (funny and romantic)
-Nobuta Wo Produce (a classic)
