Decent "B level" science fiction . Entertaining but not in the same league as Star Trek, the new BattleStar Galactica, Buffy, or Roswell. Never explained why every alien they meet speaks English, especially as language barriers were important in the original movie. Some of the acting is wooden, especially Teal'C and Carter. However, Jackson, O'Neil and Hammond are well-acted characters. The plot lines do not bear a lot of scrutiny
NEG
