Although there are a few good episodes, the second season has been a bit disappointing so far.
The Catwalk is a pleasant return to form though. The pace is good, the script has tension and wit, and there are enough twists and turns to keep us guessing.
There are a few missteps - I bet everyone of us knew the seemingly innocent aliens weren't stellar cartographers straight away! - but all in all a solid episode. True, it doesn't do much for the way of character development or contribute to a larger arc, but an engaging, entertaining story, and is real evidence that original stories like this are far superior to some of the derivative tales we've seen this season.
