That's the relationship people think they want, but in truth, it's just an annoying one note gag that lost it's charm very early on. Slight, often hypocritical jealousy with guest stars was fun... but fat joke/hiyah... that was only sort of funny in the beginning. Glad that the new movie added depth back into there. As I'd expect from someone who wrote brilliant romantic comedies, like Forgetting Sarah Marshall.
Too true.
Regarding the hypocritical part, I think that that aspect of it all has become more and more mean-spirited and doesn't seem as funny anymore, contributing further to the Flanderization of Kermit & Piggy's relationship as well as to the Flanderization of Piggy's personality.
Oh, and in addition to what I said in my previous posts, another thing that was good about her character and made her seem more human in the old days was the fact that often times, some sort of negative karma or well-deserved punishment would befall her when she did something incredibly wrong and needed to be taught a lesson (such as Kermit discovering that she paid off the audience in the Dom DeLuise episode, planting the gossip item about her and Kermit being secretly married in the Loretta Swit episode, locking Lynn Redgrave in her dressing room, etc.). Today, the pig hardly ever gets punished for doing bad things and seems to get away with murder too much--especially since today's Piggy is usually over-the-top mean and violent and enjoys going around hitting people without thinking, making her come off as a jerk-*** and REALLY well-deserving of punishment or negative karma.
I still think Eric Jacobson and Jim Lewis really should seek out serious coachings from Frank Oz on how to better approach her character and save her from her Flanderization and restore the more well-balanced personality that she had in the past.
