The more I think of the trailer, the more I realise that criticisms of the advert is pretty much a criticism of the series. The advert is one massive joke, a wink and a nudge towards the camera. This is no different to a morbidly obese man you have to assassinate in a meat-factory in Hitman or Hitman:Contracts, nor is it any different to a Blood Money advert which was the first-person perspective seeing Agent 47 ready to drop a toaster into the bath the person is in.
A good chunk of Hitman is the absurdity of it. Nothing is normal and deadly serious. You don't have a deep plot with twists and turns, filled with grit and talking about how Agent 47 is suffering internally (like every single gritty game released in the last five years, hell even Max Payne which used to conveyed a good story but winked at the ridiculous nature of it all has now stooped to something more generic (that's not to say Max Payne 3 is bad, just it's not what it used to be)). You have a bald man with a bar code on the back of his head due to him being manufactured infiltrating various places, each with an ounce of absurdity that didn't have to be there but is. You have him infiltrate a Japanese Shogan fortress, you have him infiltrate a biker place, you have him infiltrate a masquerade. These didn't have to be, especially since they don't contribute to the main over-arching story (which little of one actually exists), but are.
If you have a problem with the trailer, you really have a problem with the series and/or you missed the point of the series. If you wish to criticise it still, go for it. I give you free reign. However, it'd likely be wrong to suggest a change. You may not enjoy it, like I don't like death metal or Nintendo games, but it'd be wrong to try to please everyone.
The one troubling part of this news article though is not so much the trailer it's self, which as I said before is the game's signature, but rather the developer apologising for it. When a developer apologises for an aspect of the game, usually it ends up being changed in the future. Hitman: Absolution is finished enough where I don't have to fear it changing into a gritty shape filled with grit and brown and grey, but with apologises for frolicking in what the developer dubbed "game's natural extremism" it shows that they may be changing the game series in the future. A change to something that less winks at the camera at the sheer absurdity of it all, and is more deadpan nonsense.
If you really want an elaboration on some of the things I'm talking about here, watch the most recent Extra Credits episode: http://penny-arcade.com/patv/episode/hard-boiled Just because the example they use, Max Payne, is pretty much a series that ditched the absurdity of the plot and the wink-and-nudge approach due to the switch in developer, and went absolutely deadpan and pretty much paid for it.
