yeah, i think i know what you are saying. i believe that y'all miss the whole puzzle-scheme of this show where one evidence connects to another, which allows to assume some things and eventually get to the murderer by linking everything together. i gotta admit that i missed this kind of mystery in EE too, and as far as i remember i also complained about it last year during S6. but this season is so much better, many more things happened and it keeps me interested. in S6 we had a handful of pretty boring episodes so the fact that they didn't have this puzzle was accented a lot more. now, i don't really mind that there is less of it, but i still miss it sometimes.
you see if every episode had the perfect puzzle in it, it wouldn't be very realistic. in real life smart murderers happen quite rarely and usualy they are just plain dumbasses. the mysteries are not always solved in the way that every single piece of the puzzle is revealed, it's usually full of voids.
if CSI made a couple of episodes where there wasn't a perfect murder mystery (kinda a la Agatha Christie), and decided to do something a little different, i'm fine with that. tell me, did you anticipate this kind of ending of EE? cuz i sure didn't. it was surprising, the LACK of the puzzle was a twist nobody knew was coming.
you say that this season has been awful and different. but what about episodes like Living Legend and Burnout, the whole complicated mystery of the MCSK, the classic whodunits in Double Cross and Happenstance, or the whole Keppler case just to name a few?
i agree there was a whole lot of Cath!Drama this season and a lot of GSR for that matter. at some point S7 is the most personal yet, but also we had some amazing episodes that i would put in my Top10 anytime. don't forget that the season didn't end and i feel that some outstanding episodes are yet to come.
