After watching the first eight episodes on TV (for some reason On Demand has episodes one through eight already), I think the new ten minute run time has its ups and downs. It's definitely used to great effect in episodes six and eight. Those are the kind of episodes I hoped the new run time could bring, telling stories that wouldn't warrant a 20 minute episode. They also give the spotlight to new or minor characters, providing a nice change.
Many of the other episodes could be paired into one longer "episode," but they don't feel as complete as previous episodes. These episodes also show a potential problem, since the ten minutes seems too long, rather than too short. A few of the episodes seem to stretch a 3-5 minute sequence of a longer episode into its own 10 minute episode. While none of these episodes are outright boring, the sequences don't feel as though they should stand alone. They are still reasonably cohesive with each other, though.
So far episodes one and two seem somewhat negligible; they're not too important to the main plot. Episodes three, four, five, and seven are fun enough, especially when watched in one sitting. Episodes six and eight benefit the most from the shorter run time, since they don't really overstay their welcome. The plot is a little light so far; it seems as if small details are sprinkled throughout episodes. Hopefully they will come together more as the season progresses.
