Now this is how to update a classic TV series. If you look closely at the 2005 Battlestar Galactica, you come to the realization of what doing a "reboot" truly means. It means the creator of the new series had absolutely no respect for the original material. He liked so little of it that he threw out the baby with the bath water. Nothing was worth saving except for the barest essentials - character names and the tiniest shred of the premise. The characters themselves were completely unrecognizable. JJ Abrams' Star Trek movies are the same way. Space Battleship Yamato 2199 is the opposite. It's a remake, not a reboot. The difference is they wanted to fix or modernize a few things, but by and large had great affection for the series and kept as much of it intact as they could.
I really wanted to watch the original Star Blazers, as the show was called in the US, but alas, the time slot wasn't cooperative as it conflicted with the school day and consumer VCRs were expensive and rare in 1979, so I couldn't timeshift it. Many years later, I finally had recordings of the show, but couldn't really get more than a few episodes into it before losing interest. Still, I did eventually see the English dub of the Farewell to Space Battleship Yamato movie and enjoyed that. The live action SBY movie from 2010 again left me cold and I don't think I even finished that. If I did, it was so unmemorable that I've forgotten even watching it through to the end. To me, this remake is the best version yet, good enough for me to binge-watch the whole series in a matter of days.
