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: I gave it 2 stars because the concept was good. The design failed miserably. If this item had been made like most other products it's not an issue I would have seen and used it. The product has two sides that don't stick together well.
Example Output: Bad review

Example Input: This product works fine except the battery only lasts about 15 minutes. The power cord for the rechargeable battery can become somewhat difficult if you use this a lot and have to keep it plugged in. There are no instructions with this.
Example Output:
Good Review
