For the Mario & Luigi series, it is this game in which the returns became fully diminished. It's long, monotonous, devoid of spark and just feels stale. I get that eventually you might get to some goofy or creative stuff, but in the five hours I played all I did was traipse around boring areas where you had to find like a dozen collectibles just to get one new move. Busywork and bloat. That's all I found in my playtime. With installments like this it's no wonder people tired of the series.
