I enjoyed the new Spidey very much. I saw it in 2-D not 3-D so there are several shots that made me wish I had actually had a chance to catch it in 3-D. The film does a number of first person flying as Spidey moments that probably would have been quite fun to see in 3-D.
As a film, aside from the visual wonderment, I thought the new Spidey did a pretty good job of revising the origin story in a way that was partly more true to the comics. Gone are the organic webshooters and back are the reloadable wrist shooters. The film also breezed through more of the origin so they could better focus on developing the relationship between Peter & Gwen Stacy (no Mary Jane) and also to better develop the villain Dr. Connors. It was also nice to see the film tackle a villain that hadn't been portrayed on screen in any of the 3 previous films (not counting Dr. Connors' appearance as one of Peter's professors in Spidey 3, but he was never portrayed as Lizard).
Andrew Garfield and Emma Stone had a great believable chemistry (which makes sense as they're now dating) that helped propel the film along, and the action sequences were top notch. It's not as good as Spider-Man 2 was, but the film definitely does a great job of reestablishing the character. I look forward to more visits with this take on Spidey in the years to come.
