I'm fond of this film and it vexes me that so many "reviewers" rank it below the Peter Jackson trilogy. A filmed novel is always interpretive; in particular an animated film relies on the artist's vision and should be judged on its own terms. Speaking as a purist, this is a finer homage to Tolkien than the updated version. While this film has its flaws it stays truer to the source, especially so far as the characters are concerned.
In the Jackson version Tolkien's Frodo is barely recognizable: from the first scenes he is portrayed as a weakling, constantly wavering, manipulated by forces around him and never standing on his own two feet (this is physically and metaphorically true.) You wonder why fate chose this limp biscuit to carry the one ring to the Cracks of Doom. Jackson unforgivably rewrites Tolkien and robs Frodo of his finest moment when he allows Arwen to rescue him from the Ringwraiths...Bakshi's version respects the original, presenting a Frodo who demands the wraiths "Go back and trouble me no more!" Bakshi sustains Frodo's character as Tolkien conceived it. We see his decline as the weight of his burden increases. Frodo is so pivotal to Lord of the Rings you wonder why Jackson took such liberties (he does so with numerous characters)since character development propels the plot to its inevitable conclusion. Bakshi's film better explores the companionship between Legolas and Gimli in a few judicious scenes that are completely lacking in Jackson's version. Similarly we see Boromir horsing with Pippin and Merry, furthering the idea of fellowship. For my liking the camaraderie is more developed in the animated version than the live action.
Tolkien's poetry is an important ingredient in the novels and Bakshi makes tribute to this in one of my favorite scenes: when Frodo sings the "Merry Old Inn" song, minutes before stumbling into Strider. The cheery tune is chillingly juxtaposed with the darker theme music when seconds later, invisible to his friends but visible to the wraiths, Frodo is dangerously exposed. This is one of the most atmospheric portions of the film and chills me whenever I see it.
The well documented budget/time restrictions limit this film's final impact but had it been completed it may have resonated with more viewers. As it is, it's worth a look. Even its detractors admit that Peter Jackson derived much of his inspiration from this prototype.

Marvin(Rob Schneider)does not have the ingredients to be a cop which is his lifelong dream. But his luck changes when he has a car crush(a very bad one)and is found by a doctor. The doctor has to use animal organs to rebuild him. After this moment, he starts to have wild behaviours unconsciously and becomes a best cop one could ever be. By the time, he realises the changes and his animal instincts starts to take over his human side. In the mean time, he finds a lovely girl and try to be a perfect gentleman that means he has to control himself and behave civilised. I am not a big fun of Rob Schneider. In fact, this is the his first film I have seen. However, I can easily say that he is the best person to play the loser.(See his part in Ally Mcbeal, quite funny actually).There are some good parts in the movie such as his flirting with the goat. In such movies, the biggest problem is that the script is seems to make the viewer feel less intelligent. I am sure this movie is okay to watch as long as it is not taken too seriously. But very sad to see such films doing very good in the box office. The Animal is not the worst film I have seen to date but fails to get more than *.
