The first crossover episode, following Buffy the Vampire Slayer's 'Harsh Light of Day', I thought was a really great episode.
It was really great to see Oz in an episode of Angel, and to see how Angel reacts with news of how Buffy is doing.
Spike provided a great 'villain' for this episode, especially considering his and Angel's history together. For all those who are Buffy followers, this episode provides closure as to what happens with the Gem of Amarra, which is nice.
The torture element was great! It was so gruesome, and showed us how tough Angel really is.
This episode was also able to show us classic brooding Angel at the end, making the tough choices on how he should use the Gem.
Overall a great episode, definitely one to watch.
