I didn't like this episode when it first aired, but I watched it again this week and loved it. In his intensity, I think that Brooks was spot on in approaching the breakdown. It just seemed odd that Benny was equally coherent, which I attribute to how it was written. My biggest concern about the episode remained: it didn't clearly connect to the series as a whole. It could be an allegory about how Sisko interpreted his trials and challenges, which makes it intriguing to a series fan. On the other hand, I don't think it would tell a newcomer much about the series, the character and their conflicts.
Kudos to Alaimo and Coombs for the intense beating they hand out.
