True, it wasn't quite the same Indiana Jones, more a different character with the same name, but that's okay. It's not like I believed for a second that Sean Patrick Flanery would ever grow up into Harrison Ford.
See, I just don't get the point of that. I mean, it would be like making a SW prequel and casting as Obi-Wan Kenobi an actor who didn't resemble or sound like a young Alec Guinness or having an actor as Spock in the recent Star Trek movie who was nothing like Leonard Nimoy.
How about a Scotty who's nothing like James Doohan, a Sulu who's nothing like George Takei, a Pike who's nothing like Jeffrey Hunter, and a Sarek and Amanda who are nothing like Mark Lenard and Jane Wyatt? For that matter, Harrison Ford doesn't look much like Alec Baldwin, but he still took over the role of Jack Ryan. Naturally the priority is to find the best actor for the role. Physical resemblance is a bonus, not a requirement. Getting someone who looks or sounds right isn't enough if they don't have the talent or charisma you need.
That said, River Phoenix, who played young Indy in Last Crusade, looked and sounded uncannily like a young Harrison Ford (which also led to him playing Ford's son in The Mosquito Coast). So after having seen a young Indy who was so perfect, Flanery was admittedly somewhat harder to buy into. Had Phoenix not died tragically young, he might've been the star of this show, and it's hard not to judge Flanery in comparison to that.
I actually meant to refer to Phoenix in my original post, but forgot to! D'oh!

I agree that physical resemblance isn't entirely necessary but the new actor should capture the essence of the original. I don't regard the Jack Ryan recasting as being relevant any more than, say, the difference between the various James Bonds or Batmans (in the 1989 - 1997 movies) - there's no great continuity between any of them (e.g. Mrs Ryan was also recast, IIRC). I accept that the actors in the new Trek movie, Quinto aside, were hardly the spitting images of their predecessors, but they mostly did capture the essence of them (Urban especially). I singled out Spock because Quinto had to appear alongside Leonard Nimoy onscreen - had they not convinced as being (almost) the same man at different ages - e.g like Patrick Stewart and Tom Hardy in Nemesis - I think that would have done the movie damage.
I don't think Pegg did capture the essence of Doohan's character, as a matter of fact, and I did view his Scotty as the most disappointing of them. But at least that's merely one actor in an ensemble, recreating a role last seen onscreen almost two decades ago and first seen over 40 ago. When the lead in YIJ is playing a role who had been onscreen just a few years earlier and who is not only the lead but an iconic role, then to me it's just crazy that he never convinces you as being a younger version of the same person. Especially when Phoenix was so damn convincing in the same role, even when sharing a movie with Ford.
So I just couldn't get over that hurdle - though I might have had the series been more like the movies. All in all, I just don't see what it had to do with Indiana Jones (shrug).
