I dunno why but I do like this disaster film :) yes its totally stupid, totally unrealistic and completely along the lines of 'Armageddon under the earth' but to hell with it! its a fun ride.
Part of this is down to the likeable cast of science bods for me, Eckhart has always kinda been the bigger version of Scott Bakula in my humble view, a nice guy with floppy hair haha Karyon and Lindo are both solid as always and Tucci is fully enjoyable as the whiney scrawny egghead who will obviously kick the bucket hehe. Only downside is the Justin Bieber lookalike Swank who is just too damn wholesome and American to stand for so long.
The film is simply fun from the get go really, your typical disaster scenes across the world to the cool ideas the film makers came up with for the earth's interior, it really does feel like an updated 'Journey to the Centre of the Earth' when the crew break into a huge geode which then begins to leak lava. I think the creative team did well with whats shown as the crew progress deeper, I'm sure its wrong but it looks cool.
As you near the climax the plot does get a little more emotional as members fall by the wayside one by one much like all disaster flicks do and this does keep you glued to the screen somewhat, its very predictable but you wanna see it through.
I think the plot is well worked in this film, it seems like an impossible task but the theories of how you could actually jump start the center of the earth are clever I guess, you know its not real but it looks and sounds like it could be. I also liked the craft design they use, the 'space' suits and all the science guff they babble when the heat is on (no pun intended), a shame the ending is so flat but it beats the over blown all American showboating you got in 'Armageddon'.
