I went to see it today too. After all I had heard and read about it I was prepared for it to be a huge disappointment, but I'm a lone ranger fan so I decided to chance it anyways.
I'll echo bricker's comments above, it was fun, decent action, and overall enjoyable. While some parts were a little goofy, it was better than I expected and I was glad to have spent the time on a rainy afternoon. I would like to see a sequel where the LR gets a little more hardened in his quest for justice, becomes a better shots and is actually willing to shoot people (he doesn't have to turn into Dirty Harry, although I wouldn't mind that either). It is an origin story where the hero is dropped into being the hero unexpectedly, unlike Batman begins where Wayne had a thirst for justice from the start.
Haven't decided yet if I will buy this on Blu-ray when it comes out, but I would like to see it again at some point.
