Example Input: I'm a big fan of historical mysteries, but have found the best ones are usually those which set their books in current times (although these can still be very good too), with plots based on current events and characters who might live today, so there is much to learn about them. The Last Templar was just too unbelievable for me.
Example Output: Bad review

Example Input: It's not made for a full sized bed, so it kind of sits in middle of my son's bed.
Example Output: Good Review

Example Input: I ordered these in 2 colors....blue and purple, both of which arrived defective. The right ear piece only functioned sporadically without any input from my phone at all. Amazon is sending me a replacement pair but the same problem with second pair. Very disappointed in this product for quality control, however they were pretty great when working right. Will give it one more shot before resubmitting review. Don't buy unless you want to waste time trying out multiple pairs.
Example Output:
Bad review
