I don't think there will ever be a better effort. A sequel would be fun if it is in the contracts of the principals. However, I don't think it will happen unless there is more support by word of mouth.
I enjoyed this movie more than The Avengers. I liked both but LR was more fun. Unfortunately, teenagers who control the market and parents who want family movies were not there. The big winner of the weekend, Despicable Me II, was a rehash of the same fart jokes from DM, which I enjoyed. People like what they find familiar and The Lone Ranger is a new twist on the old westerns. Perhaps the bad guys were too bad and the Lone Ranger wasn't super human but Tonto was a strong character that deserved to be the center of attention. The origin story with Butch Cavendish was the same but a little more graphic than a TV western from 1950. I enjoyed it. Give it a chance if you are tired of Marvel Superhero remakes.
