Season 2 is now available on Amazon.
I watched the first episode last night and thought it was a solid start to the season, consistent with S1.
RT score is looking good too:

I've watched the first two episodes and as you say a solid start. But boy does this show rely on huge coincidences and stretched credibility. On a more personal note though I'm having trouble understanding why Hanna cares so much about Clara. She just seems like a bad tempered moody bitch to me.
I'm liking the budding relationship between the naive and sweet Sandy (who looks like a young Katee Sackhoff) and Jules the lesbian her wise ass fellow Utrax inmate. Sandy doesn't know what a lesbian is so I'm hoping Jules makes a move on her just to see her reaction.
