I think it's fair to say though that people's interest in Far From Home had little to do with the frequent intrusions from Happy and Fury. The film would have been every bit as good (arguably better) without them. All that stuff just seemed really superfluous.
For Happy sure, people would probably be indifferent, but I don't agree at all regarding Fury's inclusion. Looking at reactions for the trailers, people were clearly very interested in Fury's presence.
