I didn't mean that they should cut out the riddles completely, just have Matthias and Methuselah solve them faster. A couple of the riddles they spent quite a bit of time on in the book and that time could easily be consolidated into something else.
I'm not sure if you could cut out the shield since it's used to show where Martin's sword was originally kept. I guess you could completely cut that idea, though. In the book, Methuselah mentions that another told him that the Sparra had stole the sword long ago. What you could do is add a short scene in which this bird comes to Redwall, injured by Cluny's hoard, Methuselah heals him, and the bird tells them that the Sparra have the sword. Alternatively, you don't have to add anything. Warbeak told Matthias that Bull Sparra had the sword when the two first met.
I completely agree. I've said it before and I'll say it again, most Redwall books would work better with episodic nature of a TV series. I still think that, if Redwall were in theaters, it could serve as "pilot" and then the rest of the books could be adapted as a TV series again. You see popular movie cartoons pop up as TV series all the time now.To tell the truth, I'd actually like to see the series redone as a cartoon. More room for adventure! Maybe they could animate The Taggerung and The Long Patrol along the way... :P
Of course, I'm always going to say that the best Redwall movie would have had an original plot written by Brian when he was alive.
