Re: FoX Cinematic Universe
If FC wasn't made then we may not have gotten DoFP. And if The Wolverine films weren't made we may have seen even more time given to him in past or Future X-Men movies. We can now officially move forward without Logan's past being in anymore films.
They are not gonna completely ditch Logan. But they can separate him from the main team. Doing multiple films will allow these other characters to breathe. It's a good thing and will not effect the potential for the main team films. It just opens everything up for more possibilities and makes the Universe more interesting.
..and like you said not every movie needs to make a 500-billion. Profit is profit and in the end with good films will only make new characters/existing side ones more popular and bankable.
