Most of the posters who are arguing for Valve to update their source engine aren't complaining that Valve games are boring. They just look boring. Hell, if Valve all of a sudden decided to use the Unreal engine to make their games, I don't think they would magically become less fun, but they sure would look a lot better. So please, stop using your childhood love for Valve to hide the fact that the Source engine is dated and severely behind other well known engines that are just as efficient
So while you continue to support this gaming generation's Michael Bay-like obsession with special effects, me and the real gamers will support game devs that focus on making good games.
Again, developers who make good games don't always sacrifice gameplay for graphics. BC2, Oblivion, The Witcher, Half-Life 2 are just a few games that are fun to play and, at the time of their release, looked wonderful.
I understand Valve's focus is on gameplay and that the engine is placed on the back burner. But that doesn't mean that people can't call the Source engine out and identify it for what it is.
