I have to agree with many reviewers that the 5th season is disappointing. We got to know Dr. Martin as uptight, rude and cold man and still accepted him as such, because he is also a brilliant devoted doctor and a hero at times.But what's hard to accept is the fact that the birth of his love child with Louisa, a cute baby boy, did not change him one bit. In fact it doesn't make sense that he seems even more pissed off than ever in the 5th season, and there are no moments of emotional connection between him and Louisa or him and the baby what so ever.On top of that, the 3 new characters in the 5th season; the new female doctor, Martin aunt Ruth and Louisa's mother are all rather unpleasant problematic women. And the new receptionist Morwenna is just a bore.I am still looking forward to the 6th season in 2013, but really hope that Dr. Martin will loosen up and change for the better and enjoy his life with the lovely Louisa and their son.
