Wait, what? Really? I mean, seriously? Dreary Backstory is somewhat odd. The backstory didn't seem obtrusive and added a lot of motivation and personality to a lot of characters. Zero character development is just..well...did you even read the book? Practically every character is fleshed-out and everyone changes over the course of the story. The Comedian starts as a corpse, continues as a psychopath, but evolves as a more complicated character. Jon is a more obvious example. So is Nite Owl II and the Silk Spectre. Rorschach is probably the only one who could be described as static (ironically the protagonist, more or less), and he too gets fleshed out a lot over the course of the story. And if you think the ending is goofy, you simply didn't get the comic. Watchmen changed superhero comics, it was darker, more realistic and treated its characters as real beings. It was a new twist on the genre, and the ending fully showed that, as up til the very end it looks like a somewhat standard comic book finale. Until it doesn't. A lot of these things have been done a lot of times since then, but Watchmen was the first and is still one of the best.
