I REALLY hate to judge an anime before seeing how it plays out, but Persona 4 The Golden Animation is an exception.
For those of you who have neither played the original game nor scene the original anime, DO NOT WATCH THIS. The Golden Animation is trash compared to its predessecors.
For those of you who were fond of the video game and the original anime, you will be disapointed. The pacing is screwed up and they cut out a lot of important scenes. It's hard to to mention some of the scenes it skips because they are really important later on and I don't want to spoil anything. Here's what they took out (not mentiong the events that would spoil this).
-Yosuke's introduction (you don't help him out of the trash can
-Chie's introduction (she doesn't kick yosuke's ass for breaking trial of the dragon)
-Naoto Shirogane doesn't find the body (and school isn't dismissed early as a result)
-Yukiko's introduction (Yukiko, Chie, and Yosuke are just talking to Yu after class like they're good chums)
-The opening contract scene (the anime opens up with the velvet room but nothing happens. Margaret just says he's gonna make lots of friends. That's it.)
The anime skips all that and goes to the first time you go into the TV. (it also skips the portion where you find the creepy room).
I don't see how the anime could salvage the plot from here since it skipped so many important things.
