I personally think the way was lost at Resurrection, not because of the humor or overall style of the film, but because they brought weaver back. Ripley was dead, it was done. Bringing her back felt like fan-service then and it would be even more-so now if N.B.'s film were made. In the alien universe, nobody is or should be safe.
The novels, the prequels, all of it has proven well enough that you don't need dead characters to be brought back to life just to have a good alien story. Let the dead lie.
