Deus Ex: Invisible War. Yes, or no?

[everdred12a]

So, I just finished playing through Deus Ex. I never really got around to beating it up until now, but it was still a great game to play through.

My question now though, is, is Deus Ex: Invisible War worth playing? I've heard mixed reviews about the game; some people hate it for apparently deviating from the gameplay of the original (or, they said something to that effect; I dont' remember). Others I've heard love it for the simple fact it's another Deus Ex game.

So my question is - how do YOU guys think Invisible War stacks up to the original?
