I in no way meant to demean others style..... I only attempted to understand it.
I apologise if I came across as rude, then. I do believe what I said from a political and social standpoint, though. To explain...
I think there are similar reasons for the popularity of "grim n gritty" style play as there is for the popularity of arguably "negative", "dark" or "anarchist" subcultures such as punk and goth. Generally, society says that it is generally
not deemed cool or sophisticated to be happy or positive - that stuff's for kids, or musicals, or romantic comedies. The root of drama is disaster or conflict. Much alternative music, even entire scenes (such as grunge or blues) wallow in negativity, or associate intellectualism with the dark side of life. In academically acclaimed literature and movies, the subject matter is often negative "issues", and entertainment for entertainment's sake is dismissed as, perhaps, a lesser form of art.
In other words, I think that "dark" as a theme is seen as more "adult", and "happy" as "kiddie", which is something I don't take for granted. I suppose I have a chip on my shoulder when it comes to this perception, and lashed out when perhaps it was not warranted.
I don't begrudge your enjoyment of "grim n gritty", but I suppose I railed at the implication that no-one would want it any other way...and the suggestion that to not go "grim n gritty" implies the other extreme.
