I actually think the motion capture format works well for Tintin. The aforementioned action sequence with the motorbike - an astonishing feat - would have been impossible in live action.

As for Temple of Doom, I get what you are saying about Kate Capshaw, but I wouldn't say the plot has aged badly per se, as it was already aged in 1984. It was intended as a pastiche of Fay Wray scream queen types (though Fay Wray is a lot less annoying in King Kong than Capshaw is here). I always understood the joke, but I think a lot of people took it at face value at the time, so yes, it obviously is going to play a lot worse today, if one doesn't bear Lucas and Spielberg's intent in mind. Either way though, Marion in Raiders of the Lost Ark was a much better character.

On the child death front, I don't actually think any children are killed (onscreen at least) though obviously they are brutally abused and oppressed. As a child, this never bothered me, because I simply viewed it as a dark fairy tale akin to the many dark fairy tales I was exposed to as a child. Indiana Jones's heroic actions saved them (and inspired their uprising) so it ended up positive. But as a parent, one views films like this (and indeed fairy tales) with a very different eye. Temple of Doom horrifies me now in that respect (as does Oliver Twist and other stories featuring cruelty to children), but I still enjoy it through the rose-tinted spectacles of my nine-year old self.

Oh, and Spielberg's astonishingly good direction, the lavish, beautifully lit production design, John Williams's genius score, etc, etc, all raise this well above the level of mediocrity for me. :)
