If I wanted cinema, I would buy a movie. I'm a nuts and bolts gamer. Give me solid mechanics and as much playable content as you can stuff into the game. Cut scenes and flash are really not important to me at all. I still play BG1 and BG2 because they are solid games with a lot of content. The graphics are really not an issue at all.
A couple other series that went bad for graphics is Heroes of Might and Magic and Ghost Recon, Final Fantasy is hit and miss, I'm sure you guys could think of a handful of games that sacrificed gameplay for flashy graphics and half the content.
