I'm not really nervous because Perlman is gone. Writers and creative teams change for a lot of these movies.
I'm more nervous because it's always tough with sequels and finding that right balance in making a story that still both feels fresh but doesn't betray the spirit of the original.
Obviously, the work Perlman did got Guardians of the Galaxy off the ground, and that's very important. And her career seems to be doing quite well right now. She's working on Captain Marvel. So it's not like Marvel completely forgot about her and threw her aside. I feel like her contributions are recognized.
Honestly, I wish there was a way to read the earlier drafts of these movies. I wish I could've read Zak Penn's Avenger script, and the Nicole Perlman draft of Guardians just to see how different they were.
