I really enjoyed seasons 1 and 2. I couldn't stop watching. There was so much going on that it is mentally exhausting to keep track of who is who. When the 3rd season began I was almost ready to give up because I knew it was going to make things even more confusing. I powered through because I really wanted to see how it ended. I felt like they concluded it well enough that they won't need a 4th season unless they want to just make a bunch more stuff. Even if they do make a 4th I probably won't watch.
