The point of this show is that the muppets grew up with us. Sure, it's not as innocent as the original, but the content isn't vulgar or inappropriate in any way. These just aren't the muppets of 1976, and they shouldn't be. Even if the muppets are fuzzy and ridiculous, I need to relate to them or the comedy won't resonate. I don't want the muppets I loved as a kid. I want the muppets I can love now.
Regarding the controversy over the portrayal of Ms. Piggy, there's nothing inherently wrong with any character, male or female, having shortcomings, or even being betrayed in a negative light. Kermit isn't portrayed as a beacon of virtue either. By laughing at these grown up muppets with grown up problems who have to learn how to find peace with themselves and others, I get a good healthy laugh at myself.
