Overall this is a fairly mediocre film. It's short, under 80 minutes, so it's not a waste of time even if you hate it. Dead Space: Downfall is much better even though it's 3 years older. The plot is more cohesive and so is the animation style, a very important aspect.
While there can be some complaints about the plot in Aftermath (mostly regarding repetition), it's reasonably decent, and the biggest complaint is the visual aspect. The film is divided into multiple parts and each is made differently - some with 2D animation and some with 3D animation. The 3D is completely awful despite the lighting (inexcusably worse than cutscenes from some PS1 games) and the 2D is weird in the last portion (not objectively BAD, but the style isn't fitting and heavily conflicts with previous sections). Most people would probably rate this as a 7 or 8 if Aftermath used the first part's 2D animation throughout.
If you're a fan of Dead Space it's probably worth watching Aftermath, but I wouldn't recommend it; I'd recommend Downfall instead. It's not amazing, but it's much better than Aftermath in all aspects.
