The beginning of Mizutamari ni Ukabu Shima feels a bit samey compared to Boku dake ga Inai Machi with having themes of broken families and crime solving, but after a few chapters it differs enough for it to be a whole different story. Some elements still feel the same though atleast at the time of writing.
The art is what you would expect from Sanbe. You either love it or hate it. Although the artsltyle often makes characters look similar to each other.
The characters are suprisingly fleshed out even so early in the story, and somehow I don't hate the "villain"/main antagonist in the story. I actually like him and find myself rooting for him at some points.
Overall I would say that everyone who liked Boku dake ga Inai Machi should give this manga a shot and see how it turns out. I don't think it's going to top the performance of Boku dake ga Inai Machi, but I have high hopes for this one.
