I respect Ian Riley as a person, being probably the first to have a recognized mind series and making a community. Though, the series is really tough to go through, with a very underdeveloped character and jokes that sadly fall flat. If you want to watch something besides Freeman's Mind 1 and 2, I recommend Shephard's Mind over Barney's Mind.
A well-executed sequel to one of the longest-running Machinima series on YouTube. Stellar writing, stellar production. All-around a good interpretation of the mind of Gordon Freeman.
Releases are, however, very slow.
