I could understand the 4 feet bit, if it's as easy to you as walking then it becomes second nature. As Samuel L said "Been a while since you used a door" (or something like that). If you had been telekinetic for four years would you bother standing up to reach something two feet away or woul;d you just summon it to hand? Yes he could have waited for the lift to go up 6 floors but why bither, as soon as the doors shut he pops up to his room and he's saved himself time. Of course there's a risk that the lift could break down and the desk clerk would be bloody surprised that he wasn't in it, but after so many times such small risks are probably ignored.
But I quite agree about teh appearing in the middle of a street, particularly given the damaging side effects of a junp (lots of things being blown about for example). It certainly wasn't subtle at all.
A classic example was appearing in the middle of an operating room in a hospital, like that wouldn't have consequences? Although to be fair the fact that he never considered the consequences of his misue of the power was kind of the point of the film.
For me the film suffered because the leading man had such little charisma or screen presence (just like in Star Wars) and Jamie Bell was far more interesting. A film full of Jamie would have been great.
[There was also the thrown in back story that the Paladins had been hunting jumpers for centuries. One can't help but feel that in the days before CCTV, jet planes, tazers, jump gate tracking electrogizmos and hand propelled electric nets they wouldn't have stood a chance in hell.]
