The first installment was engaging, because in addition to the continuous running (implied in the title), there was a sense of mystery, regarding why these youngster were stuck in a dystopian arena. Here, they're already out of the maze, and except for the opening act, the mystery element is out, and we're left with youngsters running. And they just keep running. Running here, escaping there. Until finally, the main character says he's tired of running - even though some prominent actors show up (and one is killed for no intelligent reason). But he still promises more running for the third installment.
PS: Look up Aidan Gillen, Nathalie Emmanuel,and Thomas Brodie-Sangster. They may have been working towards a "Game of Thrones" reunion here.
