DS9 welcomes some refugees from the Gamma Quadrant.
This episode has a decent premise and a strong ending, but has some poor creative decisions and characterisation.
The refugee subject is not tackled with any subtlety, but it's a worthwhile theme for a Star Trek episode to cover. The dilemma it creates is good and the resolution for me is great. Too often you see Hollywood ending in these situations to make everyone feel good, but this is much better.
Unfortunately it's potential to be a great topical episode fails during the early scenes and the character portrayals. Too much time is wasted on language barrier issues, particularly as this has been covered in better Trek episodes before it. The Skrreea characters are generally so unlikeable you have zero sympathy for their plight and this kills investment in the outcome. I'm not sure what the point is of the Bajoran musician either.
The regular cast do well with the material they have, but I find the guest actors to be quite hit and miss.
One of the best aspects is the makeup and design of the Skrreea. The shedding skin is a great idea and brought to life well.
