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.
Growing the Beard: The general consensus is that the part of season 1 garnered a lot of negative responses (possibly a form of Hype Backlash), but from about the 9th episode, the show seemed to be finding its voice and getting better reviews.
Hilarious in Hindsight: A former soldier with a past he's ashamed of, trying (as of the end of season 1) to save his superhumanly gifted daughter from being abused and exploited by unscrupulous forces sent from a place called Columbianote The name of the capital region of the Earth Republic... will they eventually come to a lighthouse?
In-universe, Nicolette killing Hunter Bell was this for Yewll, who broke ties with her after that. Sending the Volge and trying to irradiate the town certainly weren't nice either, but the last straw, for Yewll, was killing Jarred the bartender to cover up the former. Yewll killed her to stop her from doing anything worse.
Datak's slaughter of the Spirit Riders was pretty bad, but he hits it in-universe when he scars Alak's hand for betraying him. Stahma had him beaten to a pulp and took over his business outright for that.
Pottinger may be slimey and ethically-lacking, but he really tops himself in "Painted From Memory". He paroled Yewll for the purpose of using her skills making Indogene spies that look human to create a convincing copy of Kenya, whom he would then "find" and present to a grateful Amanda. Since the process severely reduced the copy's lifespan, "Kenya" would then die and he could woo Amanda while she was vulnerable. Even Yewll found the idea sick, though she wasn't in much of a position to object. The worst part is that it worked out for him in the end, even though it didn't go exactly as planned.
As of season two, Tommy earns a place on the scrappy heap after becoming an E-Rep collaborator.
Nolan gets some hate during the second season as well. His jerkass nature has been amplified by his search for Irisa, and finding her again hasn't really helped.
Special Effects Failure: Unusually for a show like this, with consistently good and creative special effects, the Castithan makeup can be spotty at times. Sometimes you can see where the pale makeup ends and the actors' actual skin color begins (usually around the neck).
Visual Effects of Awesome: The shows effects are movie quality, and that's a huge compliment for a television series. If nothing else, because a game is being made along side it, there's likely some cross-contamination of digital assets. On the other hand, some assets are show specific - the entirety of the mines in "Down where the Dead Men Go" save for the entrance itself, interior and exterior, were CG as seen here.
Goddamned Bats: Hellbugs. Their existence is one of the game's most annoying cons. It's bad enough that they tend to pop up when fighting other enemies, but each of the different enemy types is powerful yet boring to kill: the swarmers are brittle but small and fast, the armored bugs can take a LOT of damage and explode when you finally hit their weak points (oral, boobs, and butts, and these are sometimes armored), and the archers are surprisingly weak but also surprisingly annoying with their emp / tar spitters.
The Problem With Licensed Video Games: The game's launch was rife with bugs, server issues, and lack of content, getting mediocre reviews from critics as a result. Updates have alleviated the issue to some extent.
