I also noticed the less-than-stellar effects, but it didn't distract me from the action. It's a heck of a lot better than Syfy's usual movie of the week anyway.
I said before that the Osiris had nice shiny chrome and the basestar did not, but this time I noticed that the basestar's disc was matte, but the arms were nice and shiny. Interesting decision there.
As for the Raptor's crash sequence, I could have bought it if it wasn't quite so violent. But the way it was shown, the ship should have disintegrated. Even if it didn't, the crew would be chunky salsa by now.
