Rather than a re-make this feels more like an extended cut of the first 2 Detective Conan episodes, save for a few small changes i'll list below (if you consider that to be a spoiler, you have been warned)

Overall this retelling of the start of the story was nothing short of exellent, adding a lot of prequel material and many subtle details to the cases we've seen in the past that would've never made the cut in a 20 min episode
Other interesting add-ins where getting glimpses of some of these events that unfold from other characters point of view, this works as a great way ...

Great special! I chose to watch it after finishing the original series, OVAs and movies, as this special CAN'T be watched before to have reached 800 episodes, to avoid major spoilers.

Mixed Feelings
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 ...
