Except it doesn't support all services in the "global" search, and you get spammed with all sorts of ads. I like my Chromecast with Android/Google TV, but the software experience could be a lot better.
I changed my home launcher to one like this one https://play.google.com/store/apps/details?id=org.cosinus.la...
it has made the experience much much better.
Not sure what else they'd show there. My Plex does the same thing; a list of things I can watch.
