Spirit of Justice has the same level of quality you will come to expect upon playing the rest of the Ace Attorney series. It's got satisfying mysteries both on a case-to-case basis and in it's overarching storyline. In that regard, episode 2's case stands out in particular as a fun mystery and episode 4 stands out as feeling completely out of place.

I was not really into the heavy religious/spiritual themes littered throughout this entry, but that's entirely a personal preference. There is a new mechanic in the trials that I found very interesting, but otherwise it's just more of the Wright Anything Agency's antics.

Note that this is definitely one of the longer games in the series, if not the longest. It's length is not always earned, either. Some parts can definitely drag on and there's times where you need to watch a flashback of the same dialogue like 4 times.
