I think the maypole does set the time of year and also gave SMJ something to do (which fitted in well, I think). It's light and shade. If too much of one or the other is stripped away, it's unbalanced. I really enjoyed this episode and thought the pace was good.
I'd say Dr Turner discussing a patient in the reception of the surgery without thinking is probably of the era. I like that they still put small gaffs in like that, in otherwise it would be in danger of being too modern.
I thought that Trixie getting huffy over no home birth for Lilian Reynolds due to the cancer treatment schedule was a bit jarring, as life-saving treatment would naturally need to take precedence over birth plan preferences. Trixie is a midwife so is representing the ante/postnatal treatment, but she is also a nurse who would understand the full picture.
