There are some things in life that are just plain annoying. One of the (smaller and doesn't really matter at all in the grand scheme of things) things that I find aggravating are recap episodes to t.v. shows.
You know the ones that I'm talking about. They are a montage of previous scenes mashed together--some better than others--in an effort to "catch the viewer up" with anything that he might have missed. However, there is little to no progress in the show's story arcs.
Personally, I find them insulting. If I care enough about the show to be watching it in the first place I already know the back story. I don't need an entire episode to remind me. Maybe a brief "last time on" at the beginning of an episode could be helpful if there is a particular tricky or pivotal plot development. (Shows that I have found a brief recap helpful on include, but are not limited to: Battlestar Galactica, DS9, and Lost.)
I currently watch most of my t.v. shows from Hulu or Netflix, so when there is a recap episode I normally just skip it. Or read a book, clean, cook, etc. with the television on in the background. With the shows that I watch weekly (such as The Office) it would be immensely disappointing to tune in to a recap. All that anticipation would be for nothing.
