Rough list to do because each trope always has an exception or two but I'll mention a couple that would be way different if I were to do this list. The two largest differences for me are the supernatural and love triangle. They would be the bottom of the list as least favorite. I'm sure I've watched a love triangle that was not a cringe-fest, but I can't think of one at the moment. Two that I would move up are bad timing and second chance. I'm sure there are stinkers for these two tropes but I just made a comment mentioning four movies on your Serendipity reaction and all four I mentioned fall at least partially in these two categories. Serendipity and Definitely Maybe both fall into bad timing while Eternal Sunshine of the Spotless Mind and Hi Fidelity fall at least somewhat into the second chance category. I've got to bump both up with bad timing going to God Tier for me since both of those movies would trump any bad movies in the same category.
