I was really excited about this as it is essentially a season four of one of my favorite animes, but I was extremely disappointed when I finished watching it. The pacing was completely weird because during the last episode of season four of the original, we were left on an important cliffhanger. When season one of Reawakened started, this cliffhanger is ignored and not explained until the last episode. This could easily be fixed by moving that episode from last to first. Furthermore, many characters were not mentioned or shown at any point. The reason The Disastrous Life of Saiki K is one of my favorite animes is because the comedy never fails to make me laugh and is consistent throughout the show. The only time the Remake made me laugh is when I was laughing at it instead of with it. The only reason this review has two stars instead of one is because of my immense love of the original and I cannot bring myself to very poorly rate any spin-off or extra season of it.
If you choose to watch Reawakened I would recommend watching the last episode first and then continuing with the rest of the season.
