I think they rebooted because they saw the success it did to the Batman franchise, unfortunately they're just jumping on trends. There are problems in Raimi's film series, i won't deny that, even stuff that the studio doesn't mandate, like the fact that Peter's life doesn't realy progress much, i would actualy love it to have continued with him marrying and becoming a teacher like in the comics or something like that, but i won't act as if Raimi would have done that.
That said, those films had more of a personality and love put into them, Marc Webb excells at Romance, which is also integral to Spider-Man, but at the rest, he's being pushed into doing what the studio wants, not what is better overall.
I'm sure that if he had been given the time he wanted and allowed to tell the story he wanted to tell, as well as kept improving upon the set pieces in order to make them more and more impressive, the franchise would be in a much better spot at the box-office. Bryan Singer for example was allowed to come back to the franchise he started, and was given many more resources than he had in the previous film, the result was quite impressive.
