I have been meaning to watch Free to Play for a while and I'm glad I made the time to do it. It wasn't at all what I thought it was going to be. I was thinking it was about the industry's "Free to Play" business model and games but it was actually a documentary about a group of high-level gamers playing in a professional DotA2 competition.
The featured gamers were interesting, though I'd have personally liked to see more about the teams and how they prepared as a group than the individuals, since it was a team effort rather than an individual one. I never played DotA but I think any gamer who has been part of a group involved in organized competition can probably identify here, and it honestly made me miss some old games and the days of playing with clans in leagues and tourneys.
I was pleasantly surprised to see achievements pop up for watching this! If Valve released more films in this format, I'd probably watch them. It would be pretty cool to see "highlights" after big tournaments, for example, and it might get more gamers interested in watching professional gaming.
Also I have the sudden urge to play DotA2. Well done, Valve.
