WOW! Some serious hate for that speech I see. Man... How often do we all still hear the famous speech after the attack on Pearl Harbour? Seriously, how often is that played? You've got to not watch TV for whole months at a time not to at least see a tiny bit in an add for this or that documentary or this or that veterans fund/foundation. This is 2015, pearl harbour was a 'long' time ago, particularly by contrast to the events of ID4:1 to ID4:2, 20 years difference or so I think. With that said, we'd be a weird new race of people not to be playing that speech.
It's pretty damn easy to fuck up a franchise, especially one with depth and lore to it... What's wonderful about this series is there really isn't much of either! It's a feel good, blow up the bad guys, light show extravaganza with some moments of tension and light moments of romance... It's perfect Hollywood fluff most people can at least sit through with out fidgeting. I'm excited about this... unlike Star Trek.
Personally of all the unrealistic things in this series, the return of the aliens is right up there as 'unrealistic.' If their a hive mind I'm surprised any other hive doesn't view the destruction of those ships as both a general warning signal not to approach Sol Epsilon... and good news, less competition for our desired resources! I'm somewhat surprised this movie isn't sent several hundred years in the future following a punitive expedition to large bases of alien operation, worlds, zero g ship yard and foundries... Maybe even new friends - other aliens - who are pleased that ship didn't get to move on to it's next stop, their world.
So you sort of have to view this as very light fun times. And even without Will Smith I have high hopes. What would they have done with him anyway? It's been 20 years! The man's a fighter pilot, not a strategic officer, and after 20 years he probably isn't a combat pilot. Killing him off testing craft between movies sounds about as good as you could hope for, short of grizzled and grounded squadron commander, which would just have been trite and at worst maybe a little disheartening.
