If the laid off team have been behind the CGI we've seen so far, I'm not convinced they're that big a loss.
While that's true, if CBS were running a smoother operation then their internal FX team would have been doing a better job. It never should have gotten to this point in the first place. They have work to do and the show is behind schedule.
This is starting to feel like the 21st century equivalent of the Phase II/TMP debaucle that led to having to Doug Trumbull needing to swoop in last minute and save the FX. For an FX-heavy production like this you want your FX team to be well established way early, not to bring them in so late in the game.
