If you've just finished watching S1 and, like me, were super excited to get into S2.... don't, just don't. The first episode and the last episode are fine but everything else is practically pointless. I'm not kidding,

THERE. IS. NO. POINT.

Seriously, this season is all filler to help open the plot for S3. It introduces characters and locations we'll need to know about for later but otherwise it's a complete waste of space. And if you think "oh, then surely S3 will be good and all this wasted time will be worth it!" Yeah, no, it's not so don't even bother with S3 either.

If you liked S1, do yourself a favor and pretend S2 and 3 never happened.
