Although Batman trusts the Justice League, he was always worried the day may come when one or more of them might turn, get blackmailed, or possibly just go insane and be a threat to the world (himself being no exception). Therefore, he created a special protocols for each team member that could be used to incapacitate them should that event ever arise.Vandal Savage (being one of the most intelligent villains) found a way to hack Batman's computer and weaponize these fail-safe protocols making them deadly to each team member. Recognizing that his own protocols are being used against his own team, it's a race against the clock to locate each team member, analyze what Savage did to each one, and find a way to disarm it before it's too late...My favorite part of this film was when Batman explained what he had done, he was asked how he could have done such a thing. His response -- "You mean none of you have thought of doing the same thing?" When his team implied that they would never imagine such a thing he said, "Then you're fools!"This was a very deep and intense film, and it's a must-see for DC fans or fans of superhero sci-fi in general.

This is loose adaptation of the story of the same name and I have to say this is one of the best Justice League story-lines around for it shows two things: one that when the villains can coordinate their attacks they are a force to be record with and the paranoia of Batman is a both his best weapon as he has a plan for everything and as it was shown here a weakness as it doesn't allow him to work well with others.As for the title of this review, well the team has faced a lot of crazy and dangerous event over the years ,but none of that was made with the precision of a surgeon to kill them. That is why this is maybe the worst day of the core members of the Justice League for never in their career they didn't face such a attack on them.In general the film it very fast pace, and it keeps you in interested all the way. I ,honesty, don't expect the Justice League film of this autumn to be a good as this one. In general it is a very well made story, great animation and in my point of view the best model for Metallo ever put in a video movie ,or a TV series animated or live action. If you want to see an old-fashion Justice League story ,like those from the Hustice League and Justice League Unlimited, then this a flick for you

I'm not a massive fan of comic books but I have found myself reading more of those considered "classics" as I have had more access to them than before and it has made me more interested in the genre. This has also led to occasionally checking out some of the animated films featuring the characters and brought me to this film. I don't think I've read much featuring the Justice League together as an entity and when I started watching I was a little bit put off that it included characters that I didn't particularly care for (mostly, in fairness, because I've never given them much of a chance, don't know them or have decided that based on rubbish film versions of them).Once it got going though the film was actually pretty enjoyable. It spread the load across all the characters, giving each enough action and time to fill but not too much to overload anyone or make any of them stand out as the lead. The plot is relatively straightforward but it does produce plenty of events and action and I found it pretty entertaining for what it was. The animation is colorful and accessible – personally I prefer it darker and with more menace, but again it worked for what it was. The voice cast are strong throughout – Conroy as ever but I really enjoyed Fillion, Lumby, Rosenbaum, Black, Blackthorne and many others in there, not only are they good nods to other things but they are good here.This is still an animated superhero film though and as such it is bright, full of action and fairly simple in terms of plotting and delivery; it does work though and I found it entertaining and enjoyable throughout the short running time.
