If you're into background stories of individuals, the histories of the rivalries/competition etc, and the physicality of the sport, then this is totally the show for you. It's a decent series.
But if you're hoping for an insight into the sport's rules and how the game is played to help gain an interest in the sport, then you won't get any of that.
I was hoping the creators might have followed the F1 Drive to Survive series, where that had the odd explanation thrown in, which told us what the odd rule is, or what certain tactics aim to achieve etc.
I was never a fan of F1, but I watched that series and because stuff was explained, it created an interest for me and I now see a point in watching a full race.
I don't watch Rugby matches because I find them boring and too stop-start... Plus I don't understand all the rules, so confuses me when random penalties are given.
I was hoping this Six Nations series would've chucked in some education. A bit more insight in that regard might convince me to have more interest in actual games.
Others might feel the same perhaps.
Still, I enjoyed the series because I have had plenty of experience with the rugby atmosphere thru friends, so it's not a totally alien sport to me. But to folk that's never given it a proper chance (like me with F1), it might be tough to stick with. It's not convinced me to start watching full games anyway.
