Having the Doctor represent an out of date icon of colonial masculinity (traveling around the universe fixing things because no one else can) isn't necessarily a bad thing as long as other characters are there to offer alternate experiences and perspectives. I tend to think that is the purpose of the companion and the supporting cast.
There are other directions for the show, certainly, but the existing one is perfectly valid and can even be progressive if used in the right way. I would certainly be curious to see a deconstruction of said status quo as an arc for a season or two before they jump towards changing it too dramatically.
Honestly I don't care that much though, as long as the show is well written and well performed with strong characters and interesting stories. That is what I'm watching for.
