These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Special Effects Failure: The light green hue often outlining the actors, a consequence of cheap green-screening. Heavily improved on in later seasons, but never gone. The greenscreen backgrounds themselves sometimes hit the Uncanny Valley in relation to the actors standing in them. Costuming and make-up is pretty bad early on.
Visual Effects of Awesome: The exterior starship shots, even and especially the battle sequences. It's all made in-house for the series. The battles in later seasons are truly epic. Costuming and make-up see large improvements in later seasons.
