At least in regards to the Alien franchise. Everything else they seem to be doing A-Okay with, strangely enough.
I think that's mostly because people like Ryan Reynolds (a.k.a. people that actually love the material) have control over certain properties like Deadpool... if Fox had complete control over these franchises, then we'd keep getting flops like Fant4stic and Terminator Genisys. Hopefully, Shane Black still knows what he's doing with Predator.
I think that this also happens with series and videogame franchises .
