And that's a great film, in fact one of my favourites. But it's as much a clever character piece as an alien invasion epic (as in scale, not quality).
Different films for different audiences. Escapism complete fantasy rather than a serious attempt to answer 'what would really happen if aliens landed?'
I found 'Falling Skies' very disappointing at that, despite Speilberg putting his name to it.
Going back to CGI or the dislike of it, I am a bitof a fan of this sequence ( computer controlled cameras than than computer 'imagineered' graphics ), and I'm a sad enough git to have this on the boat as 'Enterprise Clears Moorings' ...
