I love Saiki k and having read the manga and watched the anime this was a surprisingly good live action. I really enjoyed watching and it got the whole Saiki k vibes spot on. Kento Yamazaki was such a good actor!! He got saikis expressions and mannerisms spot on and I loved the story line too. Of course it wasn't the exact same as the anime it still was enjoyable.
It has the same levels of crazy from the anime and its so over the top and unrealistic so if you are not used to that you might not like it. Its super lighthearted and a great laugh. Would 100% watch again.
