Take it for what it is, and have fun!

It doesn't make sense in parts and there are plot holes but if you just accept it as a fun adventure you will enjoy it. Parts reminded me of some adventure movies I watched as a kid that were pretty unbelievable. Like Goonies and The Neverending Story. I definately laughed outloud at the mining bit and dinosaur jaw boat. Ludacris. Fun Flick though.
