'Previously on The Unit...'
I don't watch a lot of current TV, so pardon my ignorance. Is it common/does it seem weird that the... what do we call them?... teasers?... recaps? show fairly random clips from previous shows, sometimes from LONG past shows that are completely irrelevant to the current "state" of the show? Why are they even necessary when there is no current ongoing plot that needs setting up for a viewer that didn't see the episodes in question?
Also I find it interesting that these previous clips are sometimes different takes or different camera angles than the ones that made it into the final show. I think I've even seen clips of scenes that didn't even make it into the final show. I don't have a problem with this as I do with their randomness or occasional pointlessness; I just find it a bit weird that they wouldn't just use the actual final product to make the summaries. I suppose they just saved clips that they thought would be important as they were editing each finished episode, then threw them together later into recap montages, so that some stuff was preserved in the montages that was edited out of the final product.
