Finished Quantum Break. It's a decent game overall, very good at certain moments. Chapter 3 was the peak for me, with chapter 4 following it closely. Plus the TV show that goes between episodes is very well made, props for Remedy and every actor there. Now, regarding what isn't so good: chapter 2 is very boresome, the story don't pick until the next one, and this here feels completely impactless, just a bunch of meaningless fights. Then, I've to say: it has been quite sometime since I last seen a final boss battle that was this bad - honestly, it was disappointing of how dumb the fight is, and how much potential there was to make it way more interesting.
Worthy to mention too: I feel that in ch 3 and 4 the game was building momentum for another major enemy, something that Jack hadn't seen yet, but it ended not even being mentioned in the final chapter, maybe the true final boss was cut for some reason? We will never know I guess.
Overall, if you got the space, bandwidth and time, it's worth a play. I spent a total of 11 hours to finish it, and according with the game, I completed 96% of it, having in mind that, 1 hour and a half, maybe 2hrs were spent watching the live show episodes.
