“James likes to watch TV shows in his free time. He enjoys comedies and drama series with good plots. He doesn't like action movies, because they are too violent.

错误及修正：
1. “TV show's” 应为“TV shows”（复数不需要使用“ 's”）
2. “enjoy's” 应为“enjoys”（动词第三人称单数不需要使用“ 's”）
3. “is” 应为“they are”（“action movies”为复数形式）
