Extreme love for a genre is the ONLY way to make a deconstruction. If done from a place of anything but absolute adoration, you get a parody at best, and an extended version of the evil Barney song at worst.
To deconstruct something, you have to understand it well. And understanding it is so intertwined with loving it. You need to understand what makes people love it. And to have engaged with so many facets of this thing that you can recognize the conventions of the genre, the odd little assumptions made, the patterns that get repeated over and over. That takes so many hours spent with something, and so much genuine attention and care paid to it that I don't think it's even possible to make a deconstruction without loving the thing you're taking apart. You have to love something enough to take it apart to see how all of the pieces work, and it takes love to understand it well enough to be able to put it back together and still be operational. You get a deconstruction when you have someone love a type of story, go "I want to make one of my own" but they've spent too much time around the thing by now to play it straight, and understand the thing way too well to not play around with how it works. If you're just saying "Isn't it funny how every (genre) has (the tropes of said genre)?" That's not a deconstruction, that's a joke. It might be a joke that would be at home in a work of deconstruction, but it isn't enough to make a deconstruction itself. The best deconstructions are just love letters given another form.
