Not necessarily. It depends on how it’s handled. If it’s a connection via the Infinite Corridor, for example, the two series could easily stay separate but connected in a multiverse manner. You’re honestly coming across as let’s cancel this all now in case it goes bad, wah wah wah everything goes bad. You’re coming across overly pessimistic and a bit of a stick in the mud. Yes, this isn’t everyone’s cup of tea. But it is for plenty of others. But just because some people don’t like it doesn’t mean it has to be cancelled. If you don’t like it, then don’t watch it. It’s that simple.
