I didn't see Homecoming, so I can't say anything about Zendaya, but I, for one, loved Shipp as Storm. Yeah, she admittedly didn't get much to work with, but I thought she carried it easily. And she can pull off an accent (unlike Halle)!
I won't speak to the racial composition of both actresses, but Shipp just looks more like Storm to me than Zendaya. Her features are a lot softer, and that just feels more Ororo-esque to me.
As for people clamoring for a Storm movie, you guys do remember that Storm didn't get a solo (ongoing) comic series until just a couple years ago, right? And that was cancelled after a year or so, so I don't think we can blame Fox for not pulling that trigger.
What can I say but, "I love comics."
That wasn't Storms first solo title it was her second or third. Storm doesn't need a solo movie but she needs some justice, but this whole franchise save DP need that too.
If only we got Zendaya, the director would definitely give her more roles/senes/screentime in xmen dark phoenix
