For continuity reasons, it's a shame they had to recast Nebula. Also for continuity reasons, the stress helmet prop should not have been so drastically redesigned. It's only a year later, and unlikely that the station crew had a ton of extra resources for upgrades to equipment over that period given that WynComm (WyndComm?) has folded. _Stargate_ fan me laughed out loud at the general's name being Hammond. If only they'd gotten Don S. Davis to play him.
