LJ, I wasn't specifically referring to your post but there will always be some detail that is missed or incorrect, no matter how hard you try. If the film was aimed at us, I'd agree but I doubt whether a kid is really going to even notice whether mid-upper is missing or not and if they don't, does that level of detail really matter in this case? Too mush focus on detail would probably mean the programme was never done in the first place, or at least with much less scope. They want it done well enough, not perfectly.
As long it is recorded somewhere for those of use with the penchant for detail, then that is what does matter.
JMHO of course.
