One positive side of the series so far has been that there have been no Klingons in the Delta quadrant (except for the second-rate Klingon copy, aka the Kazon). And with B'Elanna there is only one half-Klingon on board the ship, who had little use for Klingon culture and drivel about heroic fights and honor in battle. A welcome change from Worf, who ultimately annoyed me massively in both TNG and DS9. He was only tolerable in PIC.
And now Voyager has to deal with 200 Klingons who have blown up their own ship in order to continue their journey on board Voyager. And as if honor, heroic songs, blood wine and gagh weren't enough, they also belong to a religious Klingon sect that sees B'Elanna's unborn child as their savior - a Klingon female J'Esh'us, so to speak. Klingons and religion - a toxic mix.
The running gags about the Klingon woman who first stalks Harry and is then wrapped around Neelix's finger are only moderately funny. Only Tuvok's reaction is amusing.
I also wonder how 200 Klingons want to colonize an uninhabited planet. There are no buildings there, they have no agricultural machinery, no medical supplies and without huge industrial replicators they would live there like the first settlers in the USA - only, unlike these Klingons, they had seeds, animals and equipment with them. Did they get everything they needed for the next hundred years from Voyager? The crew would have been busy for weeks if not months replicating everything a society needs to survive. And that's not to mention the question of genetic diversity in this population. After all, they have already only reproduced among themselves for the last 100 years.
