Now that I've had time to think it through, I actually like the change and I think it works better, since the "alien creature" from the comic would very quickly be revealed as a fake by any competent forensic scientist. Audiences have seen too many episodes of CSI to believe that every doctor and scientist in the world could be fooled by a Hollywood prop.
In my opinion, I think they just cut out the alien squid because it would have taken an extra 30min of movie time to set it all up & then reveal at the end.
That being said, the official name for the energy bombs Veidt set off? S
