Maybe you and the people you know are very used to computer modern? Complaints I hear often compare it to the fonts (and typesetting in general) of people’s preferred printers from before computer typography, so a particular typeface provided by monotype and set by a particular press.
I think a modern typeface (that is, one with contrast between thin and thick strokes among other things) is more acceptable on computers now that high-dpi displays are more common, but the resolution still isn’t perfect and that style isn’t so fashionable in most cases today.
Personally I dislike the shape of the lower case Roman t (the curl at the bottom is way too long and comes too high) and I dislike the italic u and v (as I can’t tell them apart). I think the serifs on the capital T come too low as well.
The wide array of mathematical symbols in latex don’t always go with the font and they can fail to go together well but that is a separate problem (many fonts won’t include them and the symbols weren’t all designed together.)
