1. I've seen hundreds of horror movies in my time, and I've never seen anything quite as disturbing as the final sequences of The Cove.
2. Staggeringly exposes the high-to-low complicity of many hands in the international captivity trade, though mostly it stands as a testament to one man's activist spirit and a reminder of how all social progress comes from the passion of the individual.
3. Tells you with its heart all you want to know about why it's necessary to free the dolphins from captivity and slaughter.
4. It turns out that wasn't a smile on Flipper's face.
5. [An] impassioned piece of agit-prop, which goes to great lengths to penetrate Taiji's tight security to expose this problem in gruesome detail.
6. A powerful, important and extremely well made documentary that demands to be seen.
7. An involving and persuasive film that remains frustratingly one-sided as it bandies about unsubstantiated accusations, fails to follow up on key issues and leaves you wanting to know much more.
8. Part-espionage thriller, part-documentary.
9. In this new, post-Michael Moore age of documentary filmmaking as lucrative big-screen fare, a documentary that educates without condescension, informs without bias and entertains without losing its focus is a valuable commodity.
10. If The Cove isn't in the running for next year's Best Doc Oscar, there's something terribly wrong with this world. Gripping exposé, harrowing horror-thriller and devastating agitprop, it takes us to "a little town with a big secret".

What is a brief summary of the following reviews?
Though decidedly one-sided, The Cove is an impeccably crafted, suspenseful expose of the covert slaughter of dolphins in Japan.
