I thought last night's episode was great. The fanbase seems pretty split between the complainers that demand answers NOW and the people that are content to enjoy the mysteries so long as things seem to be moving at a steady clip. Normally I'd worry about one of my favorite shows having a dwindling fanbase, but hey, the less people that watch the sooner the show will end and the sooner all the answers will come. So if you're sick of it, go ahead and tune out. It only makes things better for the faithful audience.
Juliet's backstory was excellent -- I can't wait until they do Ben. So long as they keep introducing new characters with compelling stories, I think they can keep some good momentum.
