I was on a conference call with Amanda Tapping last spring after the renewal was announced and they were actually VERY happy to only get a 13 episode order. The mega-22 episode season 3 nearly wiped all of them out, they're just not used to super long seasons for this series. I started out only being rather so-so about this series. I routinely fell asleep during episodes seasons 1-2, mostly because it just felt like a "monster of the week" show. Season 3 finally changed things and they started really building out a mythology and I thoroughly enjoy the series. I've enjoyed this season - the final 2 eps here are very much giving off a season 2 "Dark Angel" vibe to them. I don't know what's up with Magnus and her motivations. Can't wait for the finale this week to see how things shake out.
