Once again, this series' commentaries and bonus feature's volume levels stay greatly from each other and the main feature causing you to reach quickly for the remote when moving between them in order to either crank it up or turn in down. (This spans even over individual episodes with commentary...)
Wil Wheaton is back again but, thankfully, you see only one other member of the Axis for any length of time worth mentioning and, unless Miss Day wants us to really think Codex is pathetic, we shouldn't be seeing anymore of them. On the plus side, with only Mr. Wheaton to deal with, the Axis is mildly less annoying and they don't have as much of the piles of profanity.
I'm unsure why this season's commentaries also went off on how hard it was to find a bunch of different shirts... If the real people making the show don't have that many different shirts, and the character in question is jobless and short on cash, then why would she have such a selection of shirts?
I am hoping that season 5, if/when it is released (yes, I only watch this series on the DVDs), will improve and return to the earlier season's roots.
