it's been getting progressively worse for a while (last 2 OS versions) but yes, finder just wedges. finder. all sorts of other stuff more and more fragile.
i used to be able to have my desktop go a month or longer between reboots. now it's at least once a week and sometimes needs a hardware forced cold boot because it can't even just reboot.
i've been using macs since the mac +. not happy with how things have gone.
