I'm less conserned with improbable and more concerned with plot, aj.
As far as i'm concerned, if you get to hung up on "reality" when watching (or reading) scifi, you are compleatly missing the point.
Alians hiding in the Ocean, BTDT. Alians being fought with modern military equitment, BTDT. I could keep going, but it gets pretty redundent.
They've picked a plot that has been very well done in the past, and, with the mecha angle, done very recently.
So, yeah, IMHO, it's going to be boring.
Indeed.
All symptoms of a Hollywood system where movies must be pitched to a board of executives who are concerned with the bottom line to the point that I'm pretty sure movies
get pitched based on their similarity to other films. "Transformers has consistently gathered X% of the summer box office take, And Battle: L.A. with it's "aliens in the ocean" got Y%... so with similar robots, the ocean, and Michael Bay explosions, we should be able to gather Z Million dollars too..."
Or of course, if it's not that blatantly derivative, then the film is based on some other prior intellectual property, a film that's now a re-make candidate when the original earned Y, or cartoon, TV show, or comic book earned Z over it's prior run twenty years earlier.
Bleah.
I figure the "narrowcasting" of services like Netflix etc. and the net will eventually tear that system down, I hope... While summer popcorn blockbuster records, and the big Multiplexes getting creative with stuff like stadium seating, and premium food might be reversing the movie industry's slide, I'll wager the bump (if it exists, maybe I'm wrong) is only temporary.
Although, the other extreme, guys like Lucas who've got so much money they can finance their own films now and are completely independent and beholden to no one... they haven't exactly produced stellar results (cough... Jar Jar Binks) either.
