Episode 4 is a better episode to judge it on I think so I'd encourage you to give it one last chance.
3 has definitely been the worst so far and I'm not a fan of 9 (though it has some character development) but I haven't regretted watching the rest.
At this point I feel like it's basically Star Trek made more accessible to the kind of person who can't sit through Inner Light or "Shaka, where the walls fell". Tone down the moralising and philosophy (it's not entirely gone but it's definitely reduced), throw in some crude humour and you've got something that much of the US TV audience could actually watch, while still being somewhat like Star Trek to those who want it.
Maybe this kind of thing is an easier introduction for people though, and that might be a good thing.
I got through the first argument in About a Girl during the trial and it was so bad I had to turn it off. It was like they were trying to have an interesting episode that represents the best of Star Trek (The Drumhead, The Measure of a Man, Dear Doctor), but their lack of empathy, self-righteousness, terrible arguments, and no attempt to try and learn more about the other culture represented the worst of it.
That and the alien had a sudden realization of how right the humans were because he watched Santa Clause is Coming To Town.
Really frustrating to watch.
