Really hope the show comes back. And that it hasn't changed too much.
It's my favourite ever drama. I prefer the more polished mainstream US shows to the gritty, cable ones. And I felt it was one of the few shows that lasted such a long time while maintaining the same tones and high levels of quality.
Too many shows that I've loved have gone silly by the end, or, in the case of the more fantasy / Sci-fi ones, dull and complicated due to getting ever deeper into a mythology rather than keeping the perfect balance they started with (Buffy, Supernatural, etc).
Criminal Minds managed to cope with losing some of its best characters - Hotch and Gideon especially - by maintaining the solid writing and keeping the right balance between the cases and the characters home lifes, individual cases each episode v more drawn out ones, etc. I guess, yes, that makes it formulaic. But if it's a formula I like, then I'd much prefer shows to keep it then go down the familiar route of getting sillier or almost unrecognisable from how they began.
