I think this is mostly because movies are not really a shared experience any longer. The closest I've had recently to a cinema experience that you wouldn't be able to replicate at home was the end of Infinity War. Sure if you had a heap of friends over it might be close but the underlying feeling of dread, sadness, anger and confusion could be felt as you were leaving the cinema made it worth it imo.

I'm hoping Doomsday will be similar in the way it handles things but if it pulls another Force Awakens I'm gonna be annoyed.
