You may want to begin with an overall general statement referring to the major points you are going to make. You may list them all in short hand fashion or simply list a few and indicate there are others.
Examples are always helpful.
You may want to include criticisms at this point or wait until the end and have the criticisms all at once. Also feel free to discuss your own opinion, as well as other information you may have on the topic that was not available to the class. But I caution you, develop a systematic answer based on course material first, then develop your own views. You do need your own opinion, but you must show that it is an informed opinion first.
