I think SE has only really fallen when it comes to Final Fantasy which just happens to be their flagship franchise.
The TR games are good, Neir A is great, Dragon Quest has never let us down, Octopath looks like it will be fun, FFXIV online was redeemed with A Realm Reborn, etc etc etc.
The only thing they are really dropping the ball with is single player mainline Final Fantasy games (FFXV was OK, but still a ways to go for comllete redemption) and the fact that we have not had a continuation of Chrono Trigger/Cross.
