Not as good as others make out

Rating: 4/10 (20 March 2015)

So what is so special about this, I'm trying to find what other people find it so "wow, excellent, best scifi", etc etc The story is OK,,, ish, nothing special, the cgi used is OK.. (well the last 20 mins of nearly 3 hour film)
Back to the story, I don't want to give anything away, but spoiler alert im afraid here
a farmer goes back to nasa, to save the human species, and that's where it goes a bit strange Flies off to a new planet, finds out nothing there has a fight with Mat Damon, docks back at orbiting ship, flies into a black hole/sphere, all goes weird, works out He was the one contacting his daughter
Bit of a time warp paradox thing here, alien's works out it's the human race that will save themselves, because they construct something to "link" a 5th dimension
I guess by this part they tried to do a 2001 space odyssey type of film as in not much made sense and left it upto the imagination of the viewer to make sense of it, as in just random stuff going on
Then the ending, the bit this that just doesn't add up,
on the planet he went to, 1 hour was 7 years on Earth, he must of spent 2 days or more on the planet he went to, that works out to be 336 years (if it was 2 days) , but when he manages to get back home (to a future ship or something), he gets to meet his daughter who looks about 90 ish!!!!
His daughter on her death bed tells him to go find the missing crew member stranded on the planet, he steals a ship, leaves the ship/station.............and then credits!!!!!
Doesn't make sense
