Well, I'm not him, but I have found them up here in Canada and got a complete set so I'll share my thoughts on the matter. (I don't know if my local store priced them incorrectly at $4, or if that is the correct price here, but I skipped the Lego Batman series due to them being $5).
Anyway, I think the series as a whole is rather weak. Some the figures are quite boring and really don't bring much to the table. There are a few really good ones though. The Elf Princess has metallic printing and is very detailed. The rocket boy has a classic space logo on his shirt (which is hidden by the rocket, but ok) and is really nice. The French bread guy is honestly boring, but he comes with a new dog element so I like that, and the Vet comes with a new rabbit element. The butterfly girl has really nice wings, and her hair is a recolor of Wildstyles hair so that's cool.
Then there is the mystery figure (Its a highwayman by the way) which has nice printed torso, and new gun color, but I am baffled why they chose to make this one a mystery. Its no one in particular and there are 5 per box, so its not rare either.
Anyway, its not the best set ever, but it does have a few really nice figures and a lot of new interesting molds and parts that you can't get anywhere else.
