After watching this, I don't need to see the movie. We got a whole movie experience right there: mutant powers are gone, Logan is living alone and dying until he finds a broken Professor, Logan meets the little girl who is the future, they bond like a family and are pursued by cyborg policemen, fights ensue, the Professor dies, Logan and little girl continue on trying to find hope. All with Johnny Cash's classic song about a broken shell of a man. Good stuff.
You do not actually need exposition about what virus wiped out mutant powers, or how Logan found Charles, or who these post-apocalyptic government thugs are working for. You don't need to see the whole action scene where Wolverine rescues the surrogate daughter, just the one awesome dive with his claws. These two minutes are enough to paint a cohesive picture.
This ties in to the post earlier this week about the pure-imagery short stories that prologue recent Star Trek movies. We don't need more plot or backstory, we need to learn to take in and read the small details that are presented to us.
