Liked it. Definitely, in my opinion a million times better than POTC2. Granted it's not up for academy awards, but it was a good and fun film that was very entertaining.
Adressing the whole 'Star Wars' debate:
I can see where the Star Wars similarities are; but whether or not that was purposefully done that way or not is up for grabs, actually. Since the "boy being toss into a new world and destiny due to the death of a loved one" and "wandered who teaches the boy" are really just archeatypes that have been used long before and long after 'Star Wars'. 'SW' was built around these many types of archetypal characters, thus the only similarities that can be clearly drawn (I think) are the rise and fall of the Jedi order being similar to the rise and fall of the Dragon Riders. Other than that alot of it was just using the same conformed archeatypes. To really have 'copied' SW, the bad guy would have to be Eragon's real father or that (forgot her name) was his sister. But, many of those similarities that have been drawn in previous posts are actually more towards the archeatypes than 'Star Wars'...
Lucas brought up the want of using and combining these mythological archeatypal forms in one of the behind the scenes documentaries. So, if you want to do some further research just pop back in that special feature (srry, forgot the name of it) or search 'Star Wars Archetypes'.
I personally don't think 'Eragon' could be stated as being a copy of Star Wars. Yes, it used similar archetypes but the details within are different. As far as I know, might be wrong, Eragon's father wasn't the betrayer of the Dragon Slayers. Etc. Thus, it is more using the same archetypal form than it is copying off of SW.
