Charmed and Dangerous is one of the best episodes of Charmed, probably the best heavy-action episode, better than the Season 3 finale All Hell Breaks Loose. It has an atmosphere of dread throughout, together with really death-threatening situations. Also, the ending of this episode is what starts the best story-arc of the complete series (one that involves Cole) and it shows why Season 4 is the best. Yes, it might come as a surprise that it is in the middle of the season, since it seems like an obvious episode for a season finale, but the reason is that even better things are to come for The Source. Anyhow, brilliant episode, classic Charmed at it's best.
