- Azmodan/Belial - Bad at their job (lying, tactician)
- Diablo/Maghda - seeming like typical superhero villains. Wierd dialogue
- Leah dying and not being acknowledged after all the crap she has been through
- Cain is killed by Maghda (who looks like Rita Repulsa) when he is such a loved character of the series
In defense of Belial: I've come to think that the "Lord of Lies" was good enough to get into Caldeum as a mysterious baby who became Hakkan/Or he possessed Hakkan, who knows. The reason why he has been sucessful thus far is that he has been able to take over one of the greatest cities by replacing the guards/the powerful with his own minions. It would be hard for a Nephalem to NOT know what the hell is going on. I almost wonder if Belial actually wants the Nephlem to find him out - especially since he basically 'investigates' the identity of Belial as the player character moves through the act after they prove strong enough to destroy the covent and ressurect ZK's spirit. By the end of it, Belial basically wants the Nephalem to come to him and to take the stone - and the Nephalem, whether or not they read the book of the dead guard in Caldeum, always seems to know that Hakkan is Belial without anyone saying directly. So anyone who says that the whole plot of Act 2 is far too obvious for it to be a 'lord of lies' plot, do consider that the deciet has already been a success, it is just up to the Nephalem to work out where the obvious source of corruption is.
Azmodan's defense: Some people have criticized how a master tactician would announce what his next move was... I do kind of agree that Baal was a better tactician than Azmodan... Then again, at the start of Act 3, Azmodan is on the verge of destroying Bastion Keep. What he understimates is the strength of the Nephalem (as both angels and demons always tend to do). He was smart enough to send a toxic demon into the larder, not to mention you have to go through countless soul lashers and tremmors to get there (if we assume that in real life, the monsters are as strong as they are in inferno difficulty). Also, on the walls he sends those god-awful bat creature things that can potentially kill you in a couple of hits. To make it worse, you have to put up with other powerful creatures like the Phasebeasts, the bloodstar witches and the heralds. Each of these minions complement each other very well when behind a group of spear throwing/charging goats or fallen. Azmodan’s fatal flaw is of course over-confidence, as with Belial.
Now Diablo is another matter entirely. I do not really like the way he was dealt with. I am fine with the way he looks, I think it’s quite a creative and risky move, but it just goes to show that he does loosely resemble the human that he inhabits. My issue is with the voice, and the amount of dialogue he has.
In Diablo 1, we walk all the way down to hell with very little interaction with Diablo, but we know that he is the one responsible for the demons that we face. When we finally get down there, he comes out from the darkness at you saying nothing, perhaps shocking you with an apocalypse spell. In Diablo 2, he says nothing the whole game besides the rather grim human-form dialogue and “Not even death can save you from me”. Again, a main antagonist that says practically nothing. Blizzard more or less had it in the bag when it came to a very scary ‘Lord of Terror’. Even Baal with his deceitfully unimposing pantomime look and with his highly blaze’ personality is disturbing. Belial has the same effect when he transforms from his floating mephisto-like form to that humongous green thing with a deformed head. And Azmodan, well, he has been imposing since we first saw the Black Soulstone video.
Now Diablo in D3… He comes out in the open and speaks in a higher, more generic ‘bad-guy’ voice, and then mocks the player in a ‘nya nya nya’ fashion… Then when you fight him in his ‘realm of terror’, he says that you have to defeat ‘us’… Well duh! Of course we do! Rather than talking to us, why doesn’t he just leave destruction in his wake and when we face him, he just runs the hell at us to !@#$ us up? That’s how this big red demon has always maintained the title ‘lord of terror’. The best slasher films have characters who hardly ever talk, and who you only see in full about once at the end of the film. Same with ghost films, same with gore films (like Jigsaw ). They are all very limited in what they say to us because they know that they have the power. Sure the lesser evils can say a bit more, but they are masters of other things…
