Ok so now that you had time to go through the usual hate comments that are not even about the episode I am here to give an actual short review of what you will see. First of all the only downside of this episode is that it doesnt really have an ending so all I can say is about tis aspect is ONLY WATCH IT WHEN PART 2 IS OUT TOO! For the story I must say it isn't bad but not amazing either, at least for now. It does give you a nostalgic feeling so that is a plus even if it is not the meritof this exact episode but more so of the series.

Now what most people care about, animation:
All I can say is that it looks great, no matter what people might say on social media. Social media slander is just the way to feel important so don't let that fool you cause I did not see a single ugly scene.
The hate that comes to this for the animation is from the same people that would love seeing this if it was an in game cutscene so maybe keep that in mind. It looks great but you might not be used to this from an anime.

Overall a good episode and a huge step forward in visuals from the last seasons of the original series. (except the last movie of the series, that maybe looked better)
A good throwback and a catchy enough plot, even if maybe clunky at times.

As fotr the score, maybe an 8 might be a stretch for the plot but the visuals do help it. That and someone has to actually ballance out the unreasonable hate that comes to this series.
Remember, obody thinks you are cool just cause act like you hated something so just go into in with an open mind and enjoy. (again, after ep 2 comes out would be for the better)
