Dredd is really good and an almost perfect big screen adaptation of the character. It's clearly lower budget, but manages enough spectacle within its limited scope to satisfy even those who thought that it was merely a rip-off of The Raid. Karl Urban is a great Dredd, while it has good, tough supporting performances from Olivia Thirlby and Lean Headey.
Solomon Kane is a film I could watch a dozen times...and not remember a thing about it afterwards. In fact, I was looking up some information about the cast while I was watching and discovered I had actually seen it before, retaining absolutely no memory of the incident. It looks nice, James Purefoy's pretty cool, but there's nothing in the film to recommend it other than an easy, evidently forgettable, experience.
The new Conan the Barbarian retains the same forgettable quality of Solomon Kane, but it's certainly a more disappointing experience, and aside from some nice locations, left me feeling that a whole bunch of promise had been squandered. On the page, it has most of the same qualities of its older, more successful predecessors, and Jason Momoa, so great in Game of Thrones, seems a perfect fit for Conan. The problem is that everything seems so lightweight and frivolous, completely dispensing with the bleak nihilism of the Schwarzenegger films that it rather feels more like a big budget episode of Hercules than Conan proper.
