I Love Multiverse, but then again i am a fan of Micheal Moorcock, and i am interested in the science around multiple universes co-existing or multiple worlds.

There are certain things that do annoy me though like inconsitent rules or canon.

I agree for star wars though multiverse is daft. so is time travel.

In Star trek it works. In Marvel Comics or DC it works.

When you are trying to write a cohesive saga of 9 films, a family saga like the Skwalker saga it makes sense to not do multiverse, but now we have such a thing because the oot no longer exists and nor do the sequels or promised prequels which were never made and what was made was completely inconsistent with the established universe.
