My two problems with it were/are:
1. Gratuitous overuse often in inappropriate places (bad news from work, invitation to a funeral, etc.)
2. The fact that it was optimised in its hinting for low resolution screens common around the time of its creation (and its initial target, via MS Bob) making it not optimal for higher resolutions (in print, or on more modern higher resolution screens with or without sub-pixel rendering). If you are going to use that sort of font, I think there are better choices than Comic Sans itself (unless CS has had updates over the years, which, come to think of it, is not unlikely).
If you really want to wind up people who care too much about what fonts you use, try combining the two most overuses and disliked with Comic Papyrus: https://creativemarket.com/blog/designer-combines-papyrus-an... (since renamed Comic Parchment due to litigious arseholery).
Funeral invitation in comic sans (or your combo punch of comic sans + papyrus) is absolutely my vibe, brb gotta update my will to stipulate this
Jokes aside, I see a lot of either font on local small businesses' branding and it definitely makes an impression, for better or (usually) worse. I'm probably missing out on some great local businesses because I've written them off without really thinking about it until now because of using either font.
