From the vantage point of 17 years, and many sequels, I reflect on Bryan Singer's original 2000 X-Men film with genuine sadness: the recent film Logan isn't what an X-Men film should be, and moreover the past 17 year franchise hasn't been defined as a story about a group of characters, but just about Wolverine.
In 2000, the first X-Men film was dark and gritty, but charismatically so. Xavier and Wolverine were the protagonists, but so was Rogue (and Wolverine's bias in the 2000 film made story-sense, because of his link to Rogue).
Subsequent to the 2000 film, it seems that the X-Men series has been one of consistent decline, from the less charismatic X-2, to the pointless X-Men Origins Wolverine, to the dull and boring Days of Future Past.
Should the X-Men series be rebooted?
I didn't find the right solution from the internet.
