I'm not so sure about that because of all the potential interactions and crossover appeal of those movies. This new Spidey has none of that and is primarily treading on material we've all seen relatively recently.
Yeah that might help a little, but these are still going to be mostly solo movies we're talking about. And there's only so many times you can watch RDJ be a smartass, or fly around in his armor before it all feels old hat.
And frankly, I was already starting to feel that with the second IM movie.
I agree it would defintely be nice to see Spidey interact with somebody else
at some point, though. Even if it's not the Avengers or X-Men or FF. Because that's usually when he's at his most fun.
