"Great production, loss of focus, lack of good characters" That basically describes Tate no Yuusha no Nariagari.
In my opinion, an anime that has excellent production but have nothing more to offer than the production is much worse than an anime that is just bad. Tate no Yuusha no Nariagari had real potential to be a great anime or even better. With good art, great animation, and a fantastic soundtrack, but with a lack of good characters and a plot that is just boring and randomly changing and with rushed pacing. This anime becomes a much worse version of what it could have been. It just saddens me to see all of this good production going to waste. Being bad is far better than being boring.
Let us talk about the best part first. The music is Astounding both openings could be easily considered one of the best in the season. The main theme is wonderful. Kansas, Mirrors, Autoroll and many other pieces of the soundtrack are incredible. definitely, a soundtrack that I and many are going to remember and come back for.
Other than that there is not much else to say about this anime. The plot was okay in the first 4 episodes I guess, but it just didn't know where it was heading. It felt like every 3 episodes have a completely new direction for the plot. Although an ever-changing plot could be great this one doesn't even come close to that. The pacing is garbage. There are almost no good characters. All of the characters are as generic as it gets. Which in turn makes the plot that has no chance of being developed even less intriguing.
I still don't understand what does the sitting of Isekai offer to a story like this. Isekai is an interesting setting when it used for the plot rather than just being a sale tag. For example, an anime like RE: zero uses the setting of an Isekai to have a plot revolving around the concept of "respawning" which made the plot much more interesting, on the other hand in Tate no Yuusha no Nariagari there is just no reason plot-wise to have the story in another world really.
To wrap things up. This anime had the potential to be great with its production value but even with all of that, the plot and the generic characters drag this anime down and make it an overall disappointment.
