In some ways I'm very conflicted about this release, but in others, I'm very happy because it's a different perspective of the series events, and a great way to celebrate 20 years for a great mystery anime.

I don't think this is a perfect special by any means, as there are things that could have been left out, and it doesn't come off as an obvious attempt at retconning or trying to portray that Gosho had this planned out, and that's part of my discomfort with this special. There are so many things that Gosho never would have introduced in the first episode, and it read more

First things first, if you haven't watched till around episode 800, do not watch this. This special episode is not for someone who is completely new to the anime (contrary to the title). This is for those who have watched this show in its entirety. And it will spoil a lot, if you were to watch this show.

Anyways, here is the deal. To anyone who has been following the anime closely, this is practically a must watch. It hits you right in the feel. That nostalgia, those feels, the pleasure to see Ran and Shinichi goofing around, the time when Ran could smile wholeheartedly, read more

The whole episode is somewhat satisfying I rated it as 9. For me, the overall aesthetic of the narrative and phasing are a bit abrupt, but the sequencing of events are on point and so the story for the whole series became clearer/ clean.

I would say that for the viewers of detective Conan who followed it from the very beginning would find this enjoyable and satisfying but for those who dropped the series will find themselves kinda lost.

I recommend this episode for viewers who wanted to see a more clean narrative for the main story of the series because we all know that this read more

A trip down memory lane may not be the best place to start for new fans.

The premise for Episode “ONE” seems simple enough; it retells the story of how high-school detective Kudou Shinichi became the elementary school kid, Conan Edogawa. But it also goes beyond that and shows us what the other major characters were up to during that time. This is pretty fun for fans of the show, as it lets us them see what everyone was up before Shinichi gets shrunk. But what this ends up doing is introducing a lot of unnecessary details, characters and plot threads that don’t have any relevance read more
