Making references to events in prior episodes is not serialization. I don't see any serialization in the Orville so far, though they may end up doing it in the future, just like TNG did some in its latter seasons. I think GoT is the best TV series ever, so you are missing out. But I don't see much similarity between GoT and Discovery. The only influence of GoT that I see, and that is not something unique to that show, is the willingness to Kill regular or recurring characters in an attempt to make it unpredictable. I figured out Lorca was toast long before it happened.
