Everyone is allowed an opinion and the previous reviewer obviously wanted things to be revealed a bit quicker. I for one love this new series, I love that Amy and Rory finally get to stretch their acting and emotional range, I love Matt Smiths excentricities that illustrate the fierce intelligence of a timelord trapped in a body it doesnt know quite what to do with and most of all I love the steady drip feed of teasing answers that force you to go back and relive the series to see what you missed.
This series is more advanced than the previous one. Whilst that also teased you with a build up, this one works on many different levels. Steven Moffat has actually planted several seeds way back that we are only now starting to see grow. I would go so far as to say that he even adapted his stories and characters to fit things laid down by RTD and David Tennant (the last episode of this series is testimony without spoiling it).
Unlike X Files this is going somewhere and I doubt it will just run out of steam and be cancelled. This is more like Babylon 5 (tho in fairness lower budget) where there is a story arc, all will be revealed but its not for the casual viewer, and the faithful will be rewarded.
Sorry but this is by far the best Doctor, best series, best companions and best writer for a long time! I was brought up on Tom Baker and I would say that Matt Smith is second only to him. Stick with it and enjoy it.
I have only one crtiticism and that is that every now and then Steven Moffat slips and throws in something very stupid and childish that takes the edge off the drama and emotion. I know its not super serious but the whole Dalek episode in WW2 was daft and reintroducing an element of that in the last episode of this set was flawed and made the Doctor also seem a bit immature.
