I have a kind of love-hate relationship with that game. It is horrible in sooo many ways, but still kinda fun to play.
Bad traits are:
1: the game holds your hand and NEVER lets go. The first 3 Phoenix Wright-games were actually at times quite challenging, you actually had to pay attention, remember and do the connections themselves. But Apollo Justice takes for granted that the player has the attention span and memory of a 5 year old and CONSTANTLY gives you extremely obvious hints.
Never are you or the character Apollo Justice allowed to figure out the somewhat obvious things, its always another character that tells you and Apollo stands there like an idiot. Everything moves at a snails pace and when you've figured it out you will have to be prepared to wait a long time until the idiot characters also figures out the painfully obvious.
None of the characters remember things said more than 2 minutes ago. As soon as something said before is mentioned the game MUST have a bloody flashback. They literarily have flashbacks to conversationgs just minutes ago, and even though the characters should know it they are like "hmmm yeah I think they mentioned something about that". All the characters in the game suffer from constant amnesia and can never remember anything and the flashbacks are bloody constant.
2: The cases are quite strange and full of holes. I wont go into detail, but many of the cases are quite ridiculous. Especially the serenade-case.
3: Zack Gramoire is a JERK! He is Trucys father, he abandones her indefinately, screws over his partner, then when Phoenix tries to help him he makes a plan with an outside party to swindle Phoenix and beat him at poker. This would have been Phoenix's first loss in 7 years and essentially ruin his livelihood, the livelihood that supports your bloody daughter Zack! Not to mention you are supposed to be friends with Phoenix! Then when the plan fails you actually grab a bottle and hit the girl, Zack is a super-jerk.
4: Phoenix isn't Phoenix. The whole incident with the faked evidence is tenous at best, I have a hard time seeing how he could not get out of it. Then the character is just strange and boring and does not resemble the real Phoenix at all.
Ok I think thats it for now. I am looking forward to Phoenix 5 immensely, but I'm also worried. What if it has the same low standards Apollo did. I recently played Phoenix vs Layton and that game has similarly low thoughts about its players. I just dont want the game to assume that I am a juvenile idiot =(
