I know a lot of people weren't in love with Eddy Izzard's Reepicheep, but I thought he was great. I think he was better than Pegg, but to be fair, Reepicheep's lines in VDT were so poorly written I don't think anyone could have delivered them well.

Pegg's Reepicheep was too mellow and the dynamic between Reep and Eustace changed as a result. In the book, the antagonism between Reep and Eustace is very real, Reepicheep is genuinely angry at Eustace for having no respect for a knight (and a mouse and a mouse's tail!). Once Eustace has been dragoned and realizes the error of his ways, Reepicheep is the first to comfort him. The power of that is lost in the movie, because I never got the sense Reep was ever truly angry at Eustace. He seems angry right after Eustace grabs his tail, but his anger dissolves very quickly, if it was ever truly there at all. I still liked the relationship between Eustace and Reepicheep in the movie, but I like how it was done in the book better. It would have been amazing having Will Poulter's Eustace and Eddie Izzard's Reepicheep as he was in PC sharing the screen, though like Thunder-Fist said, much of the problem's with Reepicheep had less to do with Pegg and more to do with the script.

No. I never liked Eddie Izzards Reep all that much. I though Simon Pegg was a much better choice.

Absolutely! In my opinion Eddie Izzard was prefect as Reepicheep a few of the lines weren't the best but that not on the actor.

I like Simon Peg for it better. He seemed sweeter.
