I liked it, but I can see what people are saying.
I don't think he is repetitive, because every time he repeats things he adds something. Sometimes in a negative sense. Sometimes with a smirk or anti-smirk. So it isn't a straight repeat.
Anyway, why I came on was I wanted to say I loved the sketch with the giant Del Boy, and Kevin Eldon being a dense farmer. That was superb. Sometimes the sketches work very well. And I kind of liked the Del Boy routine as a whole, because I took the target as being polls that tell us what our favourite things are, rather than Del Boy. I wouldn't be suprised if Stewart Lee secretly likes the bit where Del Boy falls through the bar, and Trigger pulls a face (and, crucially cut short from Lee's version, Del gets up again and tells Trigger they have to leave).
