DD and I have just introduced my 5 year old GD to The Secret Garden by E M Nesbit. We both love it and there was a serialisation of it in the 1970s that we think has never been equalled. We now have it on DVD and DD managed also to find an easy reading version for DGD whose reading skills are not yet up to the full version.
Over Christmas we all sat in a warm huddle, DD, DDiL, DGD and me and watched it through together and loved it.
DD works in broadcasting and she commented that no one nowadays would spread a book like that over seven episodes and spend the whole of the first episode setting the scene for the main story but it was enjoyable to watch a serialisation that took its time to reveal the story and set the mood of scenes. DGD had no problem with the slow pace and watched the first three episodes in one sitting.
