I've decided to just skip Gundam since IBO & Unicorn did so little for me & having to watch it by myself will be even harder for me to deal with.
You will be missing out, Origins is nothing like the last two (besides being much better then Unicorn( which the only better then origin is that it handles battles better)).
This series more about the politics of the Universal Century, establishing the UC timeline and the major characters (especially Char) of that era of the timeline and containing Gundams anti-war message. Like the Mechs don't play much of a roll untill the last arc of the series.
That and the dub is great, Keith Silverstein is the best Char.
Also the ost is great, especially remixing old gundam tunes:
(Encounters in Space from the third Mobile Suit Gundam OVA recap)
(Mizu No Hoshi E Ai Wo Komete from Mobile Suit Gundam Zeta second opening a fav of
JadedWriter)
(Beyond the Time from Mobile Suit Gundam: Char's Counter Attack)
Which this is honestly my fav opening this season, potentially the year.
