This is a good point - I think the various forms of media available and the changing nature of digital content consumption make it difficult to contemporise any of the doctors - potentially even the new Who's given the rate of technological change. You make a fair point here and this probably makes any comparisons not as analogous as one would want.But the early doctors benefitted because there was -- give or take an anomaly with the first doctor (the first series, I think) -- no chance to see a programme after it had been on air, so viewers had no alternative but to watch if they ever wanted to see it.
Although that benefit only applies to the initial viewing bump (higher figure due to subsequent unavailability).
As long as the person reviewing actually watched the episode prior to the review then the review would be valid to me - someone is entitled to low score a review even if they did so because they don't like a female doctor or any other arbitrary reason I might disagree with - although I am not a fan of mass flag, mass spam, mass review calls from certain places as these invariably hurt the review integrity - I would be surprised if the entirety of the low ratings is due to this though.@SilentRoamer I would not take the audience figure on RT much in account as they were heavily compromised. Give a look over to certain internet places we shan't mention that organized intentional low score spam because *hurr durr female doctor hurr durr SJWs hurr durr minorities hurr durr propaganda hurr durr hates white males hurr durr oh you get the point*.
The reviews I have seen in general are majority mixed to negative and a lot of these are SFF channels I follow with reviews going back for most episode of New Who - so people with a vested interest in wanting it to succeed. A lot of these also have the same criticisms - poor writing, ancillary and unnecessary characters, heavy handed political messaging, whilst also being praised for the same things - visuals, music score, Bradley Walsh.@SilentRoamer You can look over majority of audience reviews and a lot of them are in that same vein. Most balanced reviews have it somewhere at a lukewarm score of 3/5 stars and I would put it somewhere there as well. It is a critical darling, but I think it had some serious flaws overall.
For me the biggest ratings problem would be the lack of uptick for the finale - almost all seasons see an uptick for the final episode. I think the New Years episode should give a good indication of the ratings progression as the the Daleks integrate into the new doctors tenure.
I think this also might prove that the Daleks have to be used at least once during every season in order to retain the rights to use them.
