Just why? image - The Fellowship

And this is why I dislike the Hobbit movies... The book had none of these issues!!!

i have solved this, Thranduil is 10 years earlier X) And then Legolas arrives to Rivendell and he asks for Strider, then a little boy comes and says"Im Strider" and Legolas then "The f*ck dad???", "Sorry son, my alarm clock was 10 years later, ups"

Just like almost every Elf-Lord, Thranduil was merely speaking using his gift of foresight *flies away*

Oh and because he's too beautiful to care.

Actually the "issue" here is with the LotR movies, and not The Hobbit - Jackson changed the timeline. In the book for Fellowship of the Ring, Gandalf gave Frodo the ring, told him to keep it secret, keep it safe, then left. 17 years later, he came back and sent him on his journey to Rivendell.

In the movie for Fellowship of the Ring, it doesn't seem that amount of time passed. A month perhaps. Maybe a year. But this takes 16-17 years off the whole story, putting Aragorn in his mid/late twenties at the end of The Hobbit movie.

Actually in the movies, Aragorn tells Eowyn in the Two Towers that he's 87 years old. When An Unexpected Journey Transitions out of the Prologue, it says "60 years earlier...", Therefore, by subtracting 60 from 87, Aragorn would have been about 27 years old, Making it completely reasonable for Thranduil to say this.

Realize that the movie timeline is shortened, because in the books, when Gandalf leaves Frodo with the ring after the party, 17 years pass until Frodo actually set out for Rivendell. Peter Jackson obviously kept up this timeline through the Hobbit as well. By combining book logic and movie logic, you create this issue. Realize that the timespans covered are slightly different in the movies than the books.
