While somewhat of an improvement on the first part, this conclusion to the story started a whole 9 months ago still does not come even close to the standards of the early seasons of this show.
The decision to split this in two still baffles me as Part Two certainly does not offer a complete package. What you are getting this time is 50 minutes of Tristan, Lancelot and Meliodas battling waves of demons and the culprit of the attacks Deathpierce. The story in this part is essentially meaningless as the action really is what you are here. Unfortunately though, the continual use of subpar, cheap anime game standard CGI makes even that look lacklustre.
The only real entertainment I got out of this was seeing Tristan and Lancelot a bit before their upcoming proper debut in the Four Knights of the Apocalypse (a show which promises to be far greater than this). If you have already subjected yourself to watching Grudge of Edinburgh Part One, then you can probably handle watching this too. People who are huge fans of the series may even get some joy out of watching this. But to anyone else already let down by previous seasons and movies in this series, I probably wouldn't even bother.
