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. This remake, in addition to remembering the beginning of the story, it adds many interesting details that deepen the events, added to the 2016 graphics. It also fixes some changes that unfortunately the original anime has made compared to the manga. In short, again there is little, but that little is very interesting. After more than 1000 episodes, this remake refreshes the memory perfectly. Every Detective Conan's fan should watch it, but onlyafter finished the original series.
