I think we can all agree that funny games are rare at best. But yes, I have enjoyed some games' humor: Portal, Mad World, WarioWare (various), Secret of Monkey Island, Retro Game Challenge, to name just a few. It's just that I have extremely low tolerance for Disney Channel-style humor like that in Ratchet & Clank.
As for Filmspotting, they certainly do focus on smaller films and are often disappointed by blockbuster releases, when they do review them. I don't think they are averse to mainstream films, however, and could give you a laundry list of huge movies that they enjoyed or even loved. If they crapped on recent movies like Robin Hood, Iron Man 2, and Prince of Persia, maybe it's because those films aren't very good? Even when I disagree with them (and they openly court dissenting opinions), I like hearing their arguments and getting a different perspective. If you don't like the show, don't listen to it. But if you are generally upset by opinions that don't match yours, consider why that is the case, and what harm there can really be in polite disagreement and contrasting viewpoints.
