Some potential spoilers so don't read further if you don't want to know.
Yes, it will be entertaining, but not enough to carry the franchise forward long term. It will kind of look like an Enterprise redux - Enterprise was good at the start, but then the temporal war thing got to be too much.
Lousy writers and having Berman and Braga producing is what killed Enterprise. The series got way better toward the end, but the audience was already lost. A lot of retconning took place in Enterprise, which damaged the franchise more perceived damaging that this movie created.
Remember the movie takes place in an alternate timeline so the events that we know have taken place throughout TOS, TNG, DS9, VOY will not have occurred as Kirk and crew took command way too soon. The timeline that we know from the series is still in tact, otherwise future Spock would have no memory of any of the events that he experienced.
Some people are pretty pissed though about the design of the Enterprise in this movie because it doesn't look like the TOS Enterprise. The fact is, because of the technology we have now, having a ship controlled by knobs, switches, and buttons won't make you believe it's the future.
