Except by episode 6 you've missed half the content of the season, right? Apparently it's really hard to ask for shows to at least maintain some level of consistency. I don't see why that shouldn't be extended to earlier episodes in a run. I understand why that's that much harder, but there's a reason why so many people drop off the first few episodes. Obviously shows evolve and I'm not talking about that, I'm talking about getting everything else right. Getting the context, grounding the characters in your reality, setting the correct tone etc and I imagine that in 20-30 minutes, that must be really hard to do, but it's the challenge you have to rise up to. (This isn't a dig against you, obviously, just general mutterings.)
I understand that remark about the one bored by her boyfriend and I understand her situation, but that doesn't make it any less stupid. Maybe it's just the people I've been around and their situations, but I find someone who has got themselves into that state is a bit of an idiot, needlessly. It didn't help that she also seemed like one of the more reliable/less stupid ones (the main character was clueless about reality, the younger one (Marnie?) was similarly naive, then you had the one who went travelling who seemed about as reliable as a tooth pick propping up a car that you're trying to change a wheel on).
Okay, maybe that's a poor argument. What I mean to say is is that they all felt like four different characters that instead of being individual, were highlighting specific characteristics and championing them until death, when in reality people obviously aren't that simple. The best programmes understand this hook, either detailing how someone has had that one characteristic override others and how it effects those around, or show that people are complex individuals.
Again, that's hard to convey in just under half an hour, but it didn't do anything for me. I don't know what a fair metric is to base watching a full show off of, perhaps it's longer than the first episode, but not in this case. It's funny though because I have watched numerous first episodes that have been sub-par, but I've seen something in them that I'm happy to stick to. This includes New Girl, which should completely suck, but I find hits the sweet-spot surprisingly well most of the time.
