Example Input: All in all, pretty good . All the Little Animals follows the off-kilter adventures of Bobby Platt (Christian Bale), a young man who's been left a simpleton by the long-ago car accident that damaged his brain but not his soul. He wholeheartedly loves animals and he's got a pet mouse named Peter, but Bobby has to keep Peter hidden from his wicked stepfather, De Winter (Daniel Benzali). Unable to handle De Winter's abuse any longer Bobby runs away, hitchhiking from London to Cornwall, where he meets Mr. Summers (John Hurt). Summers is a quiet man who's devoted his life to giving dead animals a reverent burial, and he trains Bobby to follow in his footsteps.     Even though the movie's title is All the Little Animals, there aren't any developed animal characters. Peter is cute, but he's out of the picture pretty quick. The rest are corpses, or depicted in wistful dream sequences (the fox is a fixture, and there's also an otter, a horse and a beaver). The human characters are sort of one-dimensional - particularly The Fat - but the actors are all superb. Benzali and Hurt's reputations precede them, but Bale is very underrated. That may change when his high-profile role of Batman hits the big screen, but as of now the general public doesn't know him. He's an actor of great range, proven by his equally convincing portrayals of simple and sweet Bobby Platt in All the Little Animals and diabolical, murderous Patrick Bateman in American Psycho shortly after.

Example Input: ......NOT GOOD ENOUGH!!!..... . I did not like hardly a thing about this war picture, Anthony Mann or no Anthony Mann [Director]...Robert Ryan was superb being in command of a motley squad of straggler/soldiers...even the macho Aldo Ray was a know-it-all who showed NO fear whatso ever [that included Army Officers also]...that's alot of claptrap...hip/hip/hooray for Hollywood...this stuff may have permeated US Army cadres in the field [ and in Hollywood studios] but it could never have happen with a US Marine squad of highly trained riflemen [13 Marines]...nary any semblence of discipline nor any sense of mission showed amongst the enlisted men in this drab Army movie...it was a foregone conclusion that most of them would be KIA by movies' end...I saw this movie in 1957; it never impressed me with what we,[I]saw and done in Korea with my Fleet Marine Force comrades in the field...many decades later, I review it with even more snickering hysterics...no way, GI...no way!!....Semper Fidelis....SSGT CHRIS SARNO-USMC FM
