If you're waiting on a new movie in order to watch the first one though Conch, I would just go ahead and watch the movie. Or just skip watching it too. It is a very straight forward adaptation of the TV show with very little meaningful or interesting changes. All the stuff with the Middle Eastern weapons broker and his shadowy organization that's subverting the NUN, Lady M and Megaroad-01 are cut from the plot entirely. The NUN is made into even more of a transparent baddie when the scene where Walkure are captured by Windermere is replaced with them being captured by the NUNS. That's kinda it. Every character and every event is basically the same with the same outcomes. It's not original or interesting enough to be a companion piece like Frontier's films were, it's just a summary in film form with some new Walkure songs. And thus it's probably the weakest film in the franchise, F7B excluded.
