I'm not just interested in a Rhodey solo movie. He has been around for so long and he is still not interesting enough to headline a solo film. Also, 2nd reason, is this could probably prolong the wait for a X-Men movie/sequels, and sequels for those who are still starting (Eternals, Shang-Chi, 4, Blade). Like realistically when do you eXpect those movies to come out especially if Marvel Studios is making movies for a dozen ips...? A War Machine movie is not essential imo, just like most Disney+ MCU shows and look how the Disney Ceo talks about those projects now...
The 2nd reason is the eXact reason why I don't want another Wolverine, Deadpool, Captain America, Thor, Ant-Man and Guardians of the GalaXy film. Not everyone should get a movie especially with all these delays happening. I want to see a X-Men film asap, and I really don't want to wait siX years for Shang-Chi 2, Eternals 2, Blade 2, Fantastic 4 Two, IF they ever get a sequel/s.
Now if you are all fine waiting til 2030 for a X-Men feature film and 2quels/3quels for the other ips, because Marvel Studios' Armor Wars needs to happen (and other MCU films), okay. I have my preference.
