One thing I wanna say before beginning my thoughts on the 14th season, I love the ending of the 13th season, and I would not change it in any way. In my opinion the ending to me was the "series" finale, where it concludes the story of RvB and is a perfect end for Church, because I always say Church as the perspective, the main character.
One thing bugs me about Season 14 being an anthology season, full of short stories, I hope if the series of episodes and stories are gonna be called the 14th season, and is a movie that people will watch to get to 15 in the future, the season should be have meaning. There should be a reason why these stories are being told, like Locus' backstory in the UNSC, for when we see him again. If it doesn't connect to season 15, then in my opinion, this next "season" should be called Red vs. Blue Anthology Series 1. Where whenever Rooster Teeth needs a break in between big arc series like Recollection and Project Freelancer, they make a little season of short stories while planning out the real next season.
I want whatever next season that will continue the Red and Blue's story line to be great, and if they need to take a break, they deserve it, it's hard making a series last 14 years. Since I'm talking about this topic, I do have theories and little fan fictions about the continuing story, and I will someday post them on my journal or on my website.
Thank you Rooster Teeth :)
