I've found this anime by random chance, and got attracted to it due to its art style, that it is kinda good for the target audience, kids.
The story on show is episodic, but vaguely connected as the plot advances to expand on the characters. The structure on the episodes it's usually that the main characters plan a heist, announce it into advance and then execute.
The way the heist is realized is usually with disguises, dispositives and gadgets, but it always amuse the viewer. The humour/comedy is the kind of thing that works for kid shows, like the sidekick getting mad at the protagonist because he
doesn't clean his room, or the antagonist hitting his head in a sign while climbing a train on movement. Simple humour but it works.
The art style is clearly focused on kids, with strong colors and characters with a good shounen style - colorful costumes and identifiable symbols. The sound has a good work by the voice actors, and the effects are good as expected.
The characters are as good as a shounen kids show is - have some flaws so you can identify, but are really good on what the show proposes. They are funny, and some with a small sad backstory, but all in a good mood.
Overall, I would recommend this show if you are looking for a simple, cheerful anime but with the protagonist winning by using his wits instead of super-powers or magic.
This review is based on the fact that I have not watched the other series, so I cannot compare the two. This review is just for the show itself, and nothing else.
This anime is fairly recent and there is only four episodes at the time of this review. I can say that I haven't enjoyed an anime as much as I did watching Kaitou Joker.
In the pros, the characters are all amazing. The creators made a good decision by not making any of the characters really perfect. The show's protagonist (or however you want to consider him), Phantom Thief Joker, makes miracles out of
thin air. But he also has flaws. He is also hot headed, sometimes denies his shortcomings and can't come to terms with his rival.
Another thing is that all of the characters are memorable. Phantom Thief Joker and Spade probably have the best design in the entire show, but the supporting characters also get some love. Like for example, Detective Oniyama is over the top and has a burning passion to capture Joker. Mister Kaneari is a self-absorbed snob. Spade is what you would probably call a gentleman of sorts. Hashi, Joker's sidekick, just wants to help.
This is not a perfect anime, mind you. While there are only currently four episodes, it would be understandable that some things wouldn't be explained. But there are some mentions of groups or organizations that we are not completely aware of. There is also the problem that sometimes, the characters could get a little annoying to listen to. This was meant for a younger audiences, and you will probably hear some catchphrases being thrown around here and there, which depending on your view, could be tiresome.
But don't let those cons ruin the show for you. This is not a show you can take extremely seriously. It is a fun, humorous show that lives in its own little world, and it executes its characters very well. Sure, sometimes there will be some annoying parts, but that shouldn't deter your experience with it.
Give it a shot, and you might be surprised with what you have.
