Nope, I didn’t. They had set it up absolutely perfectly. For the people who demand a rational explanation for everything (in a show where people fake pregnancies, people drive around in stair cars, British ethnic neighborhoods exist in Orange County, and seals bite off human hands), they’d already established that GOB had a trick planned involving water.
But the last scene was played perfectly – Michael’s going on about how he’s narcissistic and Rita says that doesn’t make any sense to her. Then she says, “you’re such a grown-up” and walks off across the pool. That’s what elevated it past make-fun-of-the-poor-dumb-retard humor into actually having something to say. A genuinely sweet message about just being happy instead of being bogged down in neuroses and worried about what other people are going to think.
It was all completely in character, too. They’d already shown how two of the only other characters who still have a trace of a soul left – Maeby and Lindsay – had been won over and were actually happy. But then as soon as they found out Rita was retarded, felt embarrassed like they’d been the butt of a joke, so Maeby has to change her love story and Lindsay has to take off her bridesmaid’s dress. George Michael saw through it all instantly, because he’s been forced to be the most mature of any of them.
Now, if they had just left it with GOB’s “No, that wasn’t my trick,” then that would’ve been schmaltzy. But if it’d just ended with Michael looking across the pool confused, it would’ve been a great moment. The “next on…” bit wasn’t terrible, it’s just that it’s the Arrested Development Formula: 1) defuse sentimental moment, 2) catch phrase from main character (‘it’s not a trick, it’s an illusion’), 3) reference video we’ve seen earlier in the episode, 4) Tobias screaming, 5) everyone’s back to being miserable, 6) comedy ensues.
It bugs me that they can’t just let a nice moment go without fear of being accused of “schmaltz,” they have to always short-circuit it. And the genius of the show is that sometimes they do the short-circuit a lot more cleverly: like in the first season, when George Michael and Michael are finally connecting as father and son over the cornballer, and Michael points out, “That’s a little cornball.”
