This new series finds a surer footing with its third episode, mainly due to its more serious tone. Paul Cornell's script might not be anything particularly original, and suffers from a fairly obvious revelation of the murderer's identity (hint: it's one of the new characters introduced, of course), but it's also constructed very nicely with a good sense of rhythm and some strong character moments.
A highlight of the series is undoubtedly Keith Allen's performances, ensuring his Sheriff a well-judged menacing bully, but with a twinkle in his eye. His scenes with Jonas Armstrong's Robin are particularly good fun, and here there is a quite excellent confrontation here after Robin infiltrates his bedroom chamber.
The merry men (sorry, "outlaws") are also quite superfluous to everything at the moment, which is a shame because there are some good young actors there. Sam Troughton gets a slice of comedy each week as Much, but everyone else just shrinks into the background -- which is a shame, because the "gang" mentality is something that should be far stronger in a Robin Hood series.
Lucy Griffiths remains wonderful as Marian, bringing heart and sincerity to the role, as well as just the right balance of old-fashioned subservience and contemporary girl power. She even gets a brief moment of action finally.
Jonas Armstrong is charismatic and engaging as Robin, although his character is somewhat castrated by the writing. As discussed, in this incarnation Robin lacks a killer instinct and is too concerned about his public image. I'd prefer to see some machismo and a shade of arrogance creeping into the nice-guy sometime soon.
Overall, Who Shot The Sheriff? is a marked improvement for the series, thanks to some stronger plotting and some cracking character interplay from Armstrong, Allen and Griffiths. The production is slick and beautiful, although it's a shame the show is so restricted regarding its tone: too bright to evoke the atmosphere you associate with the time period, while the swashbuckling is being kept firmly on a tight leesh so far. It's about time they cut loose and let the outlaws (sod it, merry men) have some fun...
