I'm inclined to agree with you there gillybob. There were far too many unfinished storylines - it's usual to leave a bit of mystery to be resolved in a future series, but this was just a little over the top.
-There's the baby - did its father die in the crash as mcem has suggested? Were any of the others in the house injured? Was it, in fact, the doctor's house the plane crashed into - if not, whose house and who was in it at the time?
-Who was the pilot? Did he die? Could it possibly have been the young mentally scarred pilot that Sarah had been hiding?
-What happens to Pat now? Will Marek think she has abandoned him because she (apparently) didn't reply to his letters? Will Marek return, or will he be reported missing in action? Actually, if the latter, Pat would probably never find out, not being a relative. Will she throttle Bob?
. Now that I'd like to see!!!
When a series ends, I really think it should end IYSWIM. This series seemed to finish in mid-sentence!
