TV Shows In Two Parts

"Cold Case" = Good Show Tonight it made me mad! I can't stand watching a show and being really into it and then "to be continued" is looking at me! Are they crazy? Now I have to wait all week for the conclusion and my brain is getting old! I'll probably forget everything by then! Why can't they warn you in the beginning? Then if you know that you won't be able to watch the following week you wouldn't waste your time watching the first half.
