I'm still currently playing the Ace Attorney games (I'm playing Rise from the Ashes right now), but I'm also watching this alongside it.

The first episode felt kind of rushed, but hey, it's an unimportant first case, and it needed to be adapted anyway because of The Thinker. Besides a few omitted details, the anime was spot on.
I thought episode 2 was much better. The pacing was good. I noticed that the anime started to deviate from strictly copying the games the added character development with Phoenix's notebook of crossed-out attorneys.

I watched episode 3 yesterday, and I was a little disappointed. The court scene was super rushed in order to fit the investigation scene in the same episode. Redd White was a lot less arrogant and intimidating (where's the punch??), and the DL-6 incident was only shown in a flashback, and not mentioned by name at all. I understand that putting both the court and investigation scene in the same episode will allow for a full-episode court session, but meh.

I also don't have a problem with the OST like many other people do. Sure, there are some original BGM, but at least they use the game BGM at all, like the cross examination theme (I think they only used Allegro so far).
Animation is meh, but a drop of quality is to be expected from a 2 cour anime.
dat euro-pop OP dat glorious ED

Rise from the Ashes might be a little different, since
Spoiler!
I actually hope they'll adapt it in a series of OVAs, or a movie, instead of including it in the anime. With the way it's going on right now, half of the show will be for Ace Attorney, and the second half will be for Justice for All, and I don't see Rise from the Ashes fitting in nicely.
