I've watched season 1.
It's a reverential and humourous ribbing of Star Trek. Similar to Galaxy Quest in many ways. Almost too close to ST, with an intro that looks like a rejected opening for Voyager.
Because it's being played in a casual manner and often for laughs, when the jokes and central conceit don't work it has to rely on the episode's plot, which can make it feel lightweight and a tad insubstantial.
But still good overall, just not as good as I had hoped it would be, though. But will watch season 2.
