I wouldn't. Deadpool is a solo movie balancing far fewer beloved characters than an ensemble X-Men movie ever will. Even then, a character like Angel Dust was just there for little more than muscle.
I understand your point but I wasn't using Deadpool as an exemple of balancing screentime. I didn't mention that in any moment. I said it was the movie where Colossus had more personality than 85% of the characters we've seen in 16 years of X-Men movies.
X-men movies are ensemble, that's absolutely right, but does that mean we'll continually see beloved characters being used as silent henchment, being killed off (some off screen), and wasted for power display? Emma, Shawn, Psylocke, Bishop, Jubilee, Angel, Banshee, Apocalypse, Havok... the list goes on.
So I don't think we can justify the lack of personality of 85% of the characters in the X-Men movies saying "well they're not solo heroes..."
And Angel Dust is another example of why I rather use Deadpool as reference. If you need a character just for "muscle", just for power display, so you can use the rest of your precious screentime to develop the characters that actually matters, Angel Dust is the perfect character to use. If you want to waste characters, chose from a D-List.
In all 3 of those cases, you have the single main lead constantly bouncing off of everyone else with the occasional side development.
Yes, they are. And Legion is a TV Show, which has a completely different structure then a movie. As I said, I want the X-Men movies to be as good as those three cases, which means I was using them as reference of quality. Reference from FOX. Because I talking about how funny it is when you criticize a decision made for an X-Men movie and you immediately labeled as a MCU fanboy.
