content: `I had to compare two versions of Hamlet for my Shakespeare class and \ | ||
unfortunately I picked this version. Everything from the acting (the actors \ | ||
deliver most of their lines directly to the camera) to the camera shots (all \ | ||
medium or close up shots...no scenery shots and very little back ground in the \ | ||
shots) were absolutely terrible. I watched this over my spring break and it is \ | ||
very safe to say that I feel that I was gypped out of 114 minutes of my \ | ||
vacation. Not recommended by any stretch of the imagination. | ||

Something surprised me about this movie - it was actually original. It was not \ | ||
the same old recycled crap that comes out of Hollywood every month. I saw this \ | ||
movie on video because I did not even know about it before I saw it at my \ | ||
local video store. If you see this movie available - rent it - you will not \ | ||
regret it. | ||

My family has watched Arthur Bach stumble and stammer since the movie first \ | ||
came out. We have most lines memorized. I watched it two weeks ago and still \ | ||
get tickled at the simple humor and view-at-life. \ | ||
This movie makes me just enjoy watching movies. My favorite scene \ | ||
is when Arthur is visiting his fiancée's house. His conversation with the \ | ||
butler and Susan's father is side-spitting. The line from the butler, \ | ||
"Would you care to wait in the Library" followed by Arthur's reply, \ | ||
"Yes I would, the bathroom is out of the question", is my NEWMAIL \ | ||
notification on my computer. | ||

I would consider cutting this paragraph and the next since it references actors by name.
