Something I found in the GoBoiano comments section, non-verbatim (and 99.9% chances I remembered it wrong):
"Key are anime from KyoAni created by Jun Maeda to make you cry."
Rewrite novel is a generic harem with lolis, and main story is something about trees
White-haired characters are too cliche.
Charlotte is the best key work.
I was impressed by Jun Maeda's work on the rewrite anime
All of these posts suck.
Just four words: Clannad After Story ED
Tomoyo After was shit, it was sold as a 18+ VN and didn't have any sex scenes for 3 arcs.
Hinoue's art was the worst so glad she left (That hurt to type...)
Clannad After Story episode 18 was the most boring thing ever.
That Choose-your-own-adventure book in CLANNAD was way better than the whole VN.
The Little Busters common route was so boring it made me drop the VN.
Yoshino, Masato and Chibimosu ain't real bros. Also who is Kotori? The one from Working?
Lucia's route was an umineko/higurashi rip-off
The mangas weren't that good.Also all the characters are straight as heck.
The only good thing about Rewrite was Lucia's titsthe rest was pretentious drug talk
My favorite Key work is Anohana.
(I have actually seen this said, more than once)
actually anohana's visual novel is the saddest and hinoue's art at that was terrible
Harmonia is Hinoue's worst work
"The only good work Key has ever made was Clannad, everything else they have written are borderline hot garbage."
(I remember this from a person on YT that commented this, but don't remember which video was)
