It is, I really liked it. By the director, music composer, and a lot of the staff that animated Attack on Titan and if you like zombie type shows and cool steampunk style. The first half of the season is really fantastic, the second half has an admittedly weak villain that a lot of fans hated that weakens it a bit as it also forces somewhat of a change of focus for a few eps but it makes a nice comeback for last couple of eps again for an exciting season finale and sets up for a season 2 that can get back to the survival stuff from the first half and sets up the main group as a group well. There have been a few reports that more is going to be made which would be great.
Also, the action is amazing.

The badass action scene from that gif is from episode 1. It's also here starting at 1:03 (or the linked 1:34 to skip the bit of buildup).
The dub is also available now and really good.
