'The Ensigns of Command' (don't quite get the relevance of that title?) is paint-by-numbers TNG. The plot must have seemed OK on paper and is executed in workmanlike fashion. However, it all comes undone simply because we never quite CARE about the fate of these colonists.
In fact, quite the contrary: they were portrayed in such a pig-headed, stupid and downright obnoxious way that I was almost rooting for the Sheliak to blast them to smithereens. The guest actors were wooden at best (and often intensely annoying) and as a result there's a shocking lack of emotional integrity at the heart of this episode. It falls flat, basically.
