the episode, Vincent-Rudzki was of the opinion that the scenes in O'Neill's house between SG-1 and Hammond "slows the episode's pace down", after what he called "a cracking start of political machinations and battles off-world", awarding 7 out of 10. Vincent-Rudzki considered the unresolved season-long arc, searching for the lost city of Atlantis to be "starting to wear a bit thin", although he otherwise applauded the second part writing "the 'wow' factor that the series has been missing too often this season is back, in force", awarding part 2 a full 10 out 10.
