I'm quite surprised at how many people are slamming this movie for historical inaccuracies, use of English, its similarity to several other films and a happy ending.
I had no problem understanding this was not a historical documentary nor did any signs point to this film being the most original sensation of the year. When I went into the film, I expected a fictional Hollywood story with a bit of action and some entertaining special effects. Guess what I got? Yes, I got a fictional Hollywood story with a bit of action and some entertaining special effects. That's all it aspired to be, it works for the film and it shouldn't be a surprise to anyone thinking of sitting through it.
On a side note, I hope the same people slamming this film for its historical inaccuracies, use of English and similarity to other works go slam Shakespeare next because these terms describe his most famous plays. As far as I am aware, they weren't speaking Shakespearean English in 13th century Verona, Italy. Anyone hear of, The Tragicall History of Romeus and Juliet by Arthur Brooke? Published before Shakespeare was even alive, I wonder if he based "Romeo and Juliet" off it?
Point is, 10,000 BC should be taken for what it is. It is two hours of Hollywood entertainment. No surprises.
