Well, I don't have a lot to add to Mark's review below. In general, the movie felt like a series of setpieces rather than a cohesive whole, and I think it mostly failed in capturing the spirit of the first film (with the exception of a couple of the stunts). The entire movie has a digitally processed sheen that gives it an unnatural golden hue, which apparently was meant to give it an "old timey" feel. However, old timers didn't employ digital tinting, so this is a bit of a contradiction in terms (I may be wrong, but I'm not going to do any research on this). Also, the CGI really stood out considering there was an unspoken promise (or maybe spoken) that the movie was a throwback employing practical effects. The reality of any stunt is called into question (even if just subconsciously) when CGI is introduced in the equation. It's like how the integrity of all of baseball was put into question when it was found that several players had been using performance enhancing drugs.
"Remarkably unremarkable" is a good way to put it, actually.
