Personally I just bought the whole X-Men series on BluRay and love them. I think the continuity of the series with the latest X-Men First Class was the best X-Men movie yet. Wolverine isn't the only Xmen character to be recieving as series you've got Deadpool and other Origin movies in the works. Then you have the possible sequels to First Class which I am guessing would be phenominal, their is no need to reboot the series a continuation would be far more preferable.
Honestly the Batman reboot is pretty good but often reboots suck. As for Spidey yah I had problems with the earlier three movies but all three were pretty good, I'm not sure that the reboot will nescessarily be better if they are great but I fear they will be worse.
I'd rather see the series continue rather then reboot. Honestly Spidey would have continued had the actors and actresses signed on for a fourth movie. But since neither of the main actors could agree on signing up for a fourth or fifth, sixth movie it wasn't like Sony or Marvel were just going to let the Spiderman license rot.
With Xmen their is no need to reboot, the originals are perfectly fine and with interchanging characters reliance on specific actors or actresses isn't as binding as say Spiderman.
