The timing is indeed unfortunate. The film's failings are more attributable to the Dredd character than the film itself; it's hard to do anything but a by-the-numbers action movie without introducing Mega-City One's more colorful characters, and in keeping the narrative grounded in "a day in the life" they denied themselves that opportunity. There's a good Dredd movie waiting to be made, but they're going to have to figure out the appeal of the comic as a whole rather than this narrow-minded focus on the one-note Dredd. If the DVD sales are enough to elevate it (and it is doing rather remarkably in the home market, much like Hellboy before it) I'd certainly watch the sequel.
