I really like this guy's version of recapping each season. Just enough to really get you into the groove without filler. His accent makes it slightly harder to understand every single word but captions are there. He's got some cute 1-liners during the narration to keep it interesting. About 20ish minutes for each season. Roughly 2 hours for 7 seasons worth.
