You're entitled to your opinion and maybe you were underwhelmed. But your questions seem like mostly things that very well were meant to question and likely will be addressed.
There were like 1000 questions in the first few episodes of S1.....so this is not a surprise to me.
Regarding yours specifically:
- Bernard. We don't know how long he was there, maybe 11-14 days maybe 1-2 hours. Who knows. I'm not sure they were whisking him to some xecution camp. They are soldiers and had orders to kill all robots I suppose. He wasn't one as far as they knew and just kinda tagged along.
- I don't think his arm was in a sling or whatever by the finale - in the tuxedo at the party. But I could be wrong. Who knows maybe they have some special medical bone healing tech we did not see. TBD.
- The whole DNA ting seems like it's a big part of the season 2 plot - would not expect it all to be answered right away.
- Charlotte, Maeve and Delores... I think that's a big part of this seasons story and you are left not knowing intentionally.
your questions just seem to want the answers of what this season is about.
