For Malefor, Hammil was perfect for that role...but they shouldn't have royaly screwed the voice with the computers....if they had used his original voice...that would have been perfect as heck.

I think Brady should have been a six maybe...but he was still pretty good. As for Cyril and Volteer....they only got one line each...so that's pretty rough stuff to judge...but if you scored them based on these facts that I just mentioned....I would have to agree.

And like I said before...they knew the series wouldn't cater to all Spyro fans....and that's what has happened. You have those that love the old ones...and ones that love the new. Then you have that very given few who appreciate both for what they are.

Answering your question (I can't speak for TEN since I havn't played it yet), the new LoS games are good, but in my opinion, what kept them from being great was mostly an irritating style of gameplay combined with how Sierra deviated from the "continue the story at your own pace" that the previous games had, into a linear quest with absolutely 0 side quests or mini-games. The boss fights were pretty fun though.

This is my personal DotD rating breakdown: (1 to 10, 10 is highest)

AUDIO: averages out to 7.8
general sound: 9
music: 9
acting: Elijah Wood as Spyro: 9
          Christina Ricci as Cynder: 9 (felt she wasn't given enough dialogue)
          Gary Oldman as Ignitus: 9
          Wayne Brady as Sparx: 7
          Malefor: 5 (because they royally screwed with Mark Hamil's actual
                           voice, poor guy. He's a great actor too. Sierra really
                           fubarbed this one)
          Blair Underwood as Hunter: 8
Screenplay/Dialogue: 6

VIDEO: averages out to 7.8
general graphics: 9
character design: Spyro: 9, Cynder: 9, Sparx: 8, Ignitus: 8,
                          Hunter: 8, Malefor: 8.5, Volteer: 7, Cyril: 8,
                          Terrador: 8, Chronicler: 8.5, Hermit: 7,
                          Prowlus: 7, Meadow: 7, Mason: 6

ENGAGEMENT: averages out to 6.75
general gameplay: 6
replayability: 6
not so challenging that you start getting irritated: 6
not so easy that you get bored after 10 minutes: 8
boss battles: 7.5
overall story: 7

Final Rating: (7.8 + 7.8 + 6.75)/3 = 7.4 (This is about a C+ on the grade scale)

Of course this is just my opinion, but I hope it helps.
The best advice I can give is rent it first and see if you like it enough to buy it. I was lucky and got it as an early Christmas gift from my older brother who gave it a 7/10.

cuz i beat it all ready on wii
