Its been a while since I did a full watch through but doesnt the case get solved in the middle of S2? I remember really liking the later half of S2 when the conspiracy stuff and all the different plotlines really got underway but I know this isnt a popular opinion

All 3 seasons are great though, but man, those first couple of 1 are dense and put me to sleep for years every time I tried starting it. Eventually I just had to sit down at 10AM on a Sunday with a (damn fine) cup of coffee and force myself through them
