Read Nickelodeon. I liked it more than Voynich Hotel. The vignette format works pretty nice with the way the guy does stories imo. And them not being part of one large story (though still connected) allowed for a lot of variety in genres and types of stories. The shortness of the stories for me at least made it difficult sometimes to actually piece together the connections though.
Edit: Just finished Kakushigoto. What a masterpiece.
! It's sad to see Kumeta so hard on himself because at least judging by SZS and Kakushigoto he is a very good mangaka. SZS managed to have a great ending after 30 volumes of silly gag manga stuff and Kakushigoto is just an amazing manga all the way through in so many different ways. It is autobiographical to some extent, though Kumeta said that Kakushi isn't really that much like him, and I don't think he has a daughter either. But he put so many of his personal experiences and opinions about the manga industry into the series and it is basically like a love letter to the manga industry. Not just in the references and such but it's so ingrained into the story at every stage, even factoring into the resolution, that as someone who is really into manga it's just really nice to see. Especially when the mangaka puts himself down all the time and has certain opinions about the industry that may make it seem like he doesn't like it. Having the mangaka's words themselves, in the form of short essays after each chapter, is just the icing on the cake and something that unfortunately the anime, among other things, can't replicate.
! And not only is it a story about manga, it's a meticulously thought out and touching father-daughter (and family in general even with the lack of a mother characters in the actual story). It twists and turns while cutting back and forth between the present and the past and building up suspense really well. If I had one complaint though it would be that (and Kumeta himself said in the manga he felt this way) the present storyline did feel like it dragged a bit. If there were even a few more scenes it might have felt like it had better pacing. It could have been darker, but it managed to be just as good the way it was, and I am glad that it stuck to the wholesomeness that it set up throughout the manga. Kakushigoto was definitely not what I was expecting coming from SZS. There is a lot that is reminiscent of SZS but that type of comedy is woven very well in with the wholesome father-daughter stuff, at times it can feel like tonal whiplash but not to the extent where it's offputting. Plot points tie in very well with each other between the present and past chapters (typically things are brought up in the present chapters and then you get what led up to it in later past chapters) and the series does a very good job near the end of firmly transitioning to the present after the final past chapters play out. There is a lot of breathtaking imagery within the last one or two chapters and like I said above, you can just feel the amount of love for the medium Kumeta has. I'm also glad it had a sort of epilogue since it seemed closer to the end that it might not. And with how good the anime is it's a shame that it wasn't able to adapt more.
