Example Input: I'm not talking about the quality of this recording, which as all previous reviewers noted, is excellent but it has been done more cheaply and crudely. Not even that far into listening to 'Live At The Rainbow Theatre', I can find no discernible differences between these two versions aside from a couple of key words on each track (a good thing). So if you already own the earlier edition, you'd be better off getting one because they're just ripping us off.
Example Output: Bad review

Example Input: We had a lot of ice in our garage for the month of December that wouldn't melt with other methods. The next morning we put on our new electric snow blower, plugged it in, turned it, and... VOILA! The top half melted. The bottom was still slightly frozen. So far only 5 snowfalls, but so far, so good. This thing is great. Here's how to get around freezing water/ice:1. Be sure you have lots and lot's and LOTS of ice.
Example Output: Good Review

Example Input: I find that the first few minutes of each movie can be really irritating, but after seeing them all through, you may just prefer some over others. I have to admit I am a HUGE fan of this movie, and would love it if we could've had commentary tracks from any cast members, especially Christopher Lloyd, which is very important in the movies. The only thing annoying was at times Peter Sellers seemed too nervous as he spoke (and laughed) during several scenes.
Example Output:
Good Review
