Millionare detective is a solid show. It isn't really anything special but it is honestly just a pretty chill and fun show to watch and sometimes that's what you need from a short anime like this. I really enjoy majority of characters and even though the main 2 guys were kinda frustrating at first they both became much much better throughout the show. Which brings up my main problem with the show is that the first half is wayyyy worse than the second half. In the first half every episode is different and honestly none of it is really memorable and it was watchable but it was mid. But the second half of the show was actually great, I really like the main plot and it gave a lot of great reasoning and backstory to most characters. I really liked how it ended aswell and it really really threw me off and was not what I was expecting at all, for a show that is really predictable I did not see the big plot twist coming. Overall this show is a bit of a mixed bag but it is really fun to watch and the perfect length for a show like this. Although i definitely would watch a season 2. 7/10
