My introduction

In the film "Gladiator" director Ridley Scott is trying to persuade his audience that even if you are the best at something and is well respected by most, there is always someone who is trying to take your spot. This shown throughout the movie beginning when we see Maximus Decimus Meridus, a well respected and honored man, leading Rome in a glorious war. Amazed by his strength and leadership qualities, the dying emperor of Rome, Maxus Aurelius, announced to MAximus Decimus that he would love and greatly appreciate it if Maximus would become emperor after he dies. As Marcus Aurelius announces his decision to his son Commodus, Commodus is deeply hurt and decides to take any necessary steps towards his father and Maximus to become emperor of Rome. Throughout the movie, Ridley Scott shows how Commodus betrays his father by killing him and plotting Maximus death to become emperor.

That is my introduction. I know I still need a conclusion sentence I am still stuck on that because I know it has to leads to the next paragraph so I am trying to think of something that is a summary of what I said that can also give me an arguable topic sentence for the next paragraph. Was my summary too short? I tried to only include a short overall summary because I did not want it to be too long but still support my topic sentence. Also, after the summary is the commentary talking about the summary and how it relates, did I do that correct or should I change it? Do it sound too much like it is suppose to be part of the summary?
