Eccleston had something undefinaeable about him which could best be qualified as unworldly. I think it's to his credit as an actor that, in a single season, he made such a powerful impression.
Yeah, Tenant wasn't unworldy in the same way Eccleston was (except when he was doing his "The Oncoming Storm" Stare, them for my money, he was-but that was an exception to the general rule), but. Tennant caried it off by his personality as well as his acting talent.
And I myself am subjective about Davison. He was
my Doctor, too, and I hated to see him go, no matter how wonderful a story
Caves Androzani was. Failure? Never!
Damn, if they could have had more Five stories like that , I'd have loved to have seen more! I read somewhere that Davison actually wavered and considered another season briefly, if he could have had more stories like that one, and I agree.
For my money,
Caves of Androzani had to be one of the top five Doctor Who stories of all time-it's just such a damned shame that Peter Davison's finest story was his last one, because he really, really shined in that one. We were really, really rooting for him and I think that's why it was so painful to see him "die" at the end.
End of Time was very good, but it didn't quite equal Holmes' script, though to be fair, RTD wasn't trying to slavishly mimic Holmes, just capture a similar tragic theme.
But the popular consensus, at least, is that he was good, but many compare him unfavorably to Baker, which I think is sad, since Five really grew on you, and I hope that will be the case with Eleven.
I think Eleven may indeed prove to be be unworldly in a more pre-Ten way, but maybe I'm swayed by his youth. He'd have to have the tremendous talent to pull it off, and of course the problem is, I've never seen him perform before, except for that brief vignette at the end of
End of Time.
So I'll wait and see, but I suspect, at best, it will take a while for Matt Smith to overcome the comparisons and establish himself. I'll be hoping for him, but I suspect he'll have a bit of an uphill battle.
