Not a fan of the episode. Both for the episode in itself and how I felt it fit into a larger trend.
Wade and Kim both use what amounts to extra creepy mind control on Monique, and then the episode ends with a stinger showing the extra creepy mind control still in use (by a new person.)
Ron's reaction to the crossdressing actually felt to me like walking back the "never be normal" Ron of the first three seasons. Actually, I kind of feel like there was a lot of rewriting Ron going on in Season 4.
They changed him from goofy mascot to impressive football player (effectively upending his bottom of the food chain position), they really seemed to back off on him being into feminine stuff, and they topped it all off with an ending where he becomes the uber-powerful world-saver of the Ron-Kim duo. That last one's not to say that Ron wasn't saving the world in the first three seasons, because he definitely was, but with the exception of the monkey power use in
Exchange and the changed-timeline-means-it-never-happened bit in
Sitch in Time Ron never did it via brute force. Kim was always the strong one who could solve problems by punching them. Ron was forced to use other means.
Ron in Season 4 really felt to me like the creators trying to have things both ways. We had that right from the start: The message of
Ill Suited is that Ron doesn't have to be a jock to be Kim's boyfriend, but the effect of
Ill Suited is that Ron is a jock for every single episode where Ron is Kim's boyfriend.
Bringing it back around to
The Cupid Effect, it ends with Kim saying she likes Ron's weird, but Ron's weird is notably absent from the episode. For a perfect example, think about the crossdressing. If this were Season 1 we'd get him liking the dress and commenting on the upsides of it. We don't get anything like that. For that particular example we get him trying to avoid it rather than seeing it as an opportunity for Ronish fun. In general, we just don't get the weird. We get Ron the *cringes* love coach. Not weird, just ... ugh.
Kim supposedly likes her boyfriend deviating from normal, but the episode goes out of its way to show that Ron isn't into what had been his longest running deviation from normal: his embrace of feminine things.
Kim gets to
say she accepts Ron even if he isn't normal, the episode gets to
show that he's totally more normal than previously indicated so Kim isn't
really stuck with a boyfriend who isn't normal.
