This ends rather suddenly. I think you need more in it about the technical codes and conventions of sitcoms – camera angles, camera movement, lighting, colour etc, and how this relates to these episodes as sitcom. You also need more specific examples from the episodes that you are studying. Some would argue that Cold Feet isn’t really a sitcom, but rather a comedy drama (a fine line between the two I think). You need some sort of definition of sitcom that you can relate your analysis to. Have a look in some of the media A Level textbooks for a chapter on sitcom………
I’m sorry this reply is late, I was away. Even if you’ve handed it in and had it marked, it’s probably still worth redoing it if it’s for a written exam, as the better your original essays are, the better you will write them again in the exam. You might not have this choice if its for coursework….
Note from editor - despite comments made to your work (download your marked work here), friends does feature a "laugh track". Also, I think a Coupling and Friends would compare better.
