Review of Steins;Gate 0
Without having read the visual novel, it is evident they tried to fit too much stuff from the many routes in a 23 episode anime, leading to a mess and many things left unexplained, especially towards the end where they realised they didn't have many episodes left and that they had to wrap it up quickly. I assume this is also the reason that it has so many blatant plot holes. The action scenes were stupid (looking at you Kagari...), the cliffhangers were unnecessary and insulting to the viewer, what little comedy there was didn't even manage to get a grin outof me most of the time, as it was either in the midst of serious scenes or had very little effort put into it.
The drama scenes ranged from ok to OMG LOOK HOW SAD/DRAMATIC THIS IS!!! OH NO THE MUSIC IS SO SAD/DRAMATIC YOU SHOULD BE CLENCHING YOUR BUTTOCKS/CRYING WATERFALLS!!1!!!!. Also, most monologues/philosophical ramblings were pretentious at best. Overall not very mature and insulting to my intelligence.
Most of the new characters had a little if not zero impact to the story and very little screen time. The one who received the most attention was Maho who remained pretty static throughout the show and I found myself not liking her for various reasons (trying not to spoil too much).Okabe later in the show had a turning moment that i felt was illogical/ happened way to quickly for plot's sake and for saving time. Because they tried to adapt too much from the novel, the characters suffered greatly in my opinion.
More importantly, all the events we saw in this season could have been entirely ignored, since they don't amount to much as far as getting us to the point where HOUOUIN KYOUMA sends the message to his past self in the original Steins;gate. It was more like a side story than what I actually expected out of this anime, leading to further disappointment regarding the absolutely horrible ending.
The original Steins;gate had a few plot related things you could nitpick but the overall execution was excellent. Comedy was funny and drama was drama.It also wisely chose to omit various routes and details, instead of failling to fit them in 23 episodes like Steins;gate 0. Time travel is near impossible to write a good story with, but Steins;gate treaded carefully, whereas Steins;gate 0 was a mess and definitely not worth your time.
Maybe the visual novel is better \_(ツ)_/.
TL;DR
Entire subplots left hanging, zero explanations, numerous plot holes, mediocre character and the ending makes zero sense. Rewatch Steins;gate and ignore this one.
