Without spoiling anything, the first season is super good and has a lot of great action. But season 1 is more like the "prologue" and action dies down in season 2, as it's more of a slow build. Season one got me interested, season 2 got me hooked.

Edit: to clarify, the show isn't really about battles/action, but it is very much included. If thats what you're looking for, season 2 might disappoint you
