Thought it was one of the weaker episodes. Obviously the bombshell at the end was great, cam and mitch's emotional scene was good, Jay&Lily&Manny were good.
The whole prom storyline just felt like filler and the take-off of the soap in the hospital was terribly contrived, didn't work and just plain wasn't funny. Of course some people may have found it funny and the above is only my opinion but felt the series deserved a better finale and was only saved with the bombshell (and Luke's hidden letters of course).
