As an action romp with monsters, Van wasn't that bad.
As for ripley 8/Amanda/david/walter and all that business, let's just have everybody be a clone. They can all meet up in the architects room from the matrix and he can tell them that they inhabit just 1 of nearly 100 parallel universes. The notion that they've ever made a truly conscious choice is inexorably, immaterial. Everything is meaningless, and the machines have almost reached acheron's core.
