I feel your premise is just wrong @Dan O'Halloran.
Does media have to be entertainment? If you asked books that, you'd leave out probably the best literature can offer.
What is important is that it is in some way meaningful, significant, that it says something.
I understand that you don't mean trashy silly, or comedic ridiculous, but assuming there should be evasion and not introspection is a massive belittlement of the range of experiences that we can imprint into our current media, and a disservice to yourself as a thinking person.
You not only fail to answer your question: Is it good television? but you fail to actually review the episode in any meaningful way other than projecting a prejudice about your intended continued carelessness for what the show might mean.
Also, by declaring that life's too short you imply that there should be more important things to be doing other than watching a grim TV series? reflecting on transcendental matters?
Do you mean that life should be passed more light-heartedly? Do you understand that games, art, tv, books and all sorts of human expression are in fact unnecessary and you could consider ALL of that unworthy of spending your time in?
Is light time wasting better than thoughtful time wasting? you seem to imply so. And that's just wrong.
EDIT: Now, keep in mind that I don't think this is the best show ever or much less, I'm concerned with the handling of mystery (hoping it does not follow what happened with LOST).
I also hope they don't use unnatural communication as a plot device, since a lot of the characters seem to be incapable of actually speaking to one another as normal human beings.
About the plot, I think that 2% of the population disappearing seems a bit low, and could have less of an impact socially than what they imply, but of course, this is still a drama fantasy series, so suspension of disbelief is still viable, at least for me.
On the technical side, there were two very particular musical montage moments, which although excellently shot, I believe were heavy handed and disjointed the narrative without much purpose. I love James Blake and all but I thought it was out of place and unnecessary.
However, all things considered I also believe they have nailed the melancholy, the subtlety and made the conflict quite enticing beyond the simple grief, there is much in the way of motivations and secrets that could definitely pay off in the longer run.
