Meh.... WTH was that? And no continuation next week? So what exactly was the point???
With only a few hours left, they should be building up to a finale, not waste time on a bizarro future. Poor makeup and effects didn't help. And turning the observers into villains makes no sense - especially villains hanging out in a fancy bordello. Ugh. Do they really think that turning observers into low-rent nazis would be compelling? Not for me.
No, I'm not digging this at all. One of the worst episodes of Fringe IMO, even if the girl was very cute.
Mo vote is sadly: BAD.
