I don't see her talents either. She's vastly overrated (and many online blogs and lists also say this). She doesn't even pop up on lists of the hottest stars of the moment.
But the studio clearly wants her. They even developed that Red Sparrow spy movie to keep hold of her. Whether it's Kinberg who wants her back, or studio bosses, I'm not sure, but it's worth noting how some producers and execs attach themselves to certain actors (Jackman, Reynolds, Tatum are the obvious ones with this franchise).
The trouble is they'll have to renegotiate, she'll want more money (and possibly have certain conditions written into her contract on the blue make-up) and they'll have to justify the big paycheck with a prominent role in the story. You don't pay someone $20m for a cameo.
Also worth noting in that Cinemablend interview with Hutch Parker is mention of "some of the younger characters that we introduced last time" returning. Note the word some. That jives with certain rumours that were floating around. I just hope they leave doors open for a later return of the ones they don't include rather than kill them off like Emma Frost and Banshee.
The mention of Rogue is interesting. At this point they're beyond caring about continuity, lol...
