PROBLEM: Review: I don't hand out ten star ratings easily. A movie really has to impress me, and The Bourne Ultimatum has gone far beyond that. Furthermore, this trilogy has come together so nicely, that I believe it to be one of the greatest motion picture trilogies of our time. Though all three films could not be any more different from the Ludlum novels, they still stand as a powerful landmark in cinematic achievement. The Bourne Ultimatum made me want to cry that the series was complete, yet I could not even attempt to stop smiling for hours.From the moment that the opening title appeared, I knew we were in for a ride. Paul Greengrass has done it again. Everything we love from the previous Bourne films is here once again: the action, the dialogue, and of course the shaky camera. However for me, that last one was never a problem. I think it adds to the suspense.I will be back to see this film several times before it is released on DVD, simply because it is genius. It is a perfectly satisfying conclusion, and should stand the test of time as a fantastic movie, and altogether, an unforgettable trilogy. Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: In ten words or less to describe this film, Barbara Stanwyck is too appealing and it is great! The film is wonderful, except for the perhaps tacked-on ending, but I love happy endings anyway. Barbara Stanwyck, however, as the platinum-blonde gold-digger is amazing. She knows what she wants and goes after it! This film is sexy and excellent! Question: is it a negative review?

SOLUTION: no

PROBLEM: Review: It's been a looooonnnggg time since I saw this comedy, and I'd forgotten just how idiotic it is. I'd place this easily in the lower two or three of Elvis Presley's very worst movies. Presley plays Joe Whitecloud, a half-breed Indian bull rider who returns home to Arizona and the broken-down shack where his family lives, and where his friends love to party all night long. His parents are played by Burgess Meredith and Katy Jurado, and his old Indian grandpa is Thomas Gomez. None of the three offer anything of substance , comically or otherwise. The government has invested in the family's cattle, but they're lacking a bull. Elvis gets to sing just a few utterly worthless songs, and is pursued by a young boy-crazy gal and her gun-toting mother. This is just a real slapdash of a mess, and the dilapidated surroundings practically stink of manure and don't make this much easier. The one thing that puzzles me, however, is that Elvis actually seems to be having a good time in the film. Hard to believe, considering he got so upset about being stuck making so many mediocre movies. Question: is it a negative review?

SOLUTION:
yes
