Season 3 will surely be announced soon. Obviously, it will. The writer has this habit of introducing major cliffhangers and plot twists right when the season finale is about to end.
Okay so right off the bat, I'll say that season 2 is very different from 1. Not just in tone, but in a lot of ways this season is just different. If you don't accept that, you won't like this season because it's not like what you're expecting.
I loved it. I thought this season was innovative, intense, action-packed, full of plot twists and cliffhangers. It kept me on my toes throughout the 11 weeks that it aired. The weekly experience was absolutely amazing with this anime in particular and I'll tell you why. It's not just because of the cliffhangers (which obviously, just like season 1, were amazing).
The major reason though is the storytelling, which was highly impressive. It's a very different non-linear way of storytelling that completely took me off guard. There was a point around episode 6 I think, where I was very confused about what was going on. This story will tell you something major that happened, and then it will later slowly explore what exactly happened before that, while also exploring the back stories of all these new side characters. It was around episode 9 or 10 where it just suddenly hit me, that the story makes almost complete sense now. There was just a point where the puzzle pieces automatically found a way to fit together. That's why the weekly experience was so much fun.
The soundtrack for season 2 is absolutely amazing, full of new tracks. The action is jaw-dropping and just surprised me. The quality of the hand-to-hand combat scenes was just off the charts. The amount of emotion poured into the story is right up there with season 1. Though, it's a lot more intense and darker than the 1st season.
I would highly recommend Link Click, because it's one of the best modern anime out there. And if you love crime, mystery and time travel shows, GO WATCH IT!!!
