I almost fell asleep watching this crap. (Spoilers?)
This movie is eye candy and nothing more. Much of it is beautiful to look at, but there is no story whatsoever. The sad thing is that I was really loving it up until they got to the Steam Castle, and then the whole thing turned into a total waste of time.
What the hell was the hero's father trying to achieve? He makes all these grandiose speeches about how the steam ball is this amazing source of limitless energy that will end human toil and suffering forever. But apparently all he can think to use it for is to make a giant mountain of iron fly through the air, then park it in the center of London and wait for it to explode. And boy did it ever take a long time to explode. It seemed like the last half of the movie is people running around inside the dark steam castle, opening or closing valves to make the boiler explode. Or not explode, it was hard to care after a while. At that point it became harder and harder to stifle my yawns and keep my eyes from closing. When the Steam Castle does finally explode, what are we supposed to feel? Are we supposed to think "Thank goodness the nineteenth century was spared the evils of steam power!"
Of course movies like this are dazzling to some people, in the same way a shiny pull-tab from an old beer can is dazzling to the common magpie. And like the common magpie, they will start screeching with rage if you try and take away their shiny thing. They will read my opinion and say
"Whaddaya mean it had no story? It had an amazing story, you just don't get it 'cause you only like Hollywood movies where everything is like all explained and stuff. Only sensitive geniuses like me and my internet friends can understand this kind of deep stuff, so you should just stick to movies like Dude Where's My Car? or Bowling for Columbine. Only sensitive geniuses can see the beauty of the Emperor's New Clothes!"
To that I can only say that I'm rather old fashioned, and I like to have at least a few scraps of plot and character development with my retina sugar.
