I hardly even noticed Black Tom. At least the Juggernaut got some screen time.

I loved juggernaut in this movie. It was awesome how they introduced him and connected him to Charles Xavier. It was a quick line in the movie, and so happy they did it. All they needed to do.

Better than The Last Stand. And Charles Xavier and Cain Marko were complete strangers to each other in that movie, which was a disappointment.

Testing revealed audiences wanted more time with Cable (Josh Brolin) and Domino (Zazie Beets) and so reshoots on the movie beefed up their onscreen time

I think we needed even more time with them than we got. Especially Cable's arc at the end, when he decides to save Deadpool and stick around, makes pretty much zero sense. There were too many characters in this movie. The whole plot of the first act should have been over in, like, five minutes.

Cable needed more development. There was no hint about who his parents are--Scott Summer and Madalyne Pryor.

HOLY COW, I didn't know that Scott and Maddy had a little kid. I must be showing how out of touch with the books I am in a big way.

Yes, he's the offspring of Scott and a Jean clone. The movie never mentions this, even though Scott is seen briefly with the other X-Men at the X-Mansion.
