Review of Steins;Gate 0
Don't watch this. I find it irritable to say the least to read so many good reviews of this, which are obviously just borrowing fame from the first series. I honestly wonder how much can something we enjoyed make us turn a blind eye to every fault it produces afterwards, and why should it, since this is a different series from the first! So what did we enjoy in the first series? Hououin Kyoma's persona, the romance with Kurisu, the d-mails to the past, and the perplexed, nuanced and dexterous story-telling. Now forget EVERYTHING, because this series has absolutely none of the things we loved inthe first, and not any redeeming qualities by itself whatsoever.
Kyouma is dead because Okabe is depressed (which would have been a nice idea if handled correctly - and it was most certainly not), the romance is being ridiculed by adding Mahou and trying to persuade us that she has feelings for Okabe by shoving it down our throats, and the Kurisu AI is the main one at fault for that, the time-travelling is saved for the end and it's absolutely ridiculous, and the story-tellling is just horrendous. Almost all of the previous faults could have been forgiven if each and every episode (aside from the episode Okabe and real Kurisu meet again briefly) wasn't such a chore to watch! It was boring, the storyline with Kagari made absolutely no sense, the bad guy was cartoonish and too obvious from the get go, all the episodes were really badly structured, so none of the angst the series repetitively screamed that you should feel, managed to elicit any kind of emotional reaction from the viewer.
Like all of the above shouldn't be considered enough, this thing is barely moving. This gets even worse when they tried to add in action scenes. It was pretty sad seeing Suzuha trying to move and do things while the budget wouldn't let her. The sound, well, it was there I guess. OP was ok.
If this didn't have the name "Stein's Gate" on it and its fame to carry it, it would have been lost in the depths of our conscience the next day it finished airing. Seeing it rank so high, I can't help but feel of how unfair this is to much better series that don't get the recognition they deserve. The first Stein's Gate is worthy of being one of the most beloved anime series to recent date. This thing here, has absolutely nothing to do with it.
Bottom line: Don't watch. Especially if you liked the first series, it will leave a really bad aftertaste. It was never needed in the first place, but it didn't manage to add a single good thing in the franchise. Just rewatch and enjoy the first series if you need a reconnection.
