I will say that this one wasn't as great as the first, but sequels rarely are. That said, it's still a good movie and, like the first one, the 3-D effects are awesome! Both the Turtle's Tale movies are great examples of what 'Amazing 3-D' is. If you like pop-outs, things flying out of the screen, then you need to pick this movie up. You won't find the first one here on Amazon, at least I haven't been able to yet (with US region coding). You can find it on Netflix if you search for it on a 3D device (like a 3-D BluRay player). After I saw that one I came straight to Amazon and picked up this sequel.
I love these movies not only for the amazing 3-D, but I have a real passion for the ocean and ocean life, and this movie really puts you under the sea. It has a great message and communicates the importance of caring for our oceans and our environment. Good story, good music, good message, great 3-D. Pop over to Netflix and check out the first while you have the second one coming via Amazon Prime.
