Oh yes. There are a couple of episodes of Enterprise that had WANT rather than NEED in mind and it was just.... nonsense The good thing is with the way the stories are being told and less episodes per season there'd be no need to dig into the toy box. All the elements they need will be ni the concept, and each episode will tie to that concept instead of shrugging and saying "Right chaps, we've nothing next week. Ideas?" I think it'd be much easier to avoid those past mistakes by having the series plotted out in advance like most shows these days, instead of winging it.
