Blacklist is an alright game. However, what I realize in every stealth game lately is that they are broken and too easy. The major culprit is, actually, the "press [X] for successful takedown" button. Sadly, every stealth game seems to have that feature these days.
What I've also come to realize while playing Blacklist is that an even easier and more broken option is ghosting. "What!?" Yes, ghosting. I've literally ran (albeit crouched) through CHUNKS of levels while ghosting. All you need is timing; adaption; expertise in controlling Sam Fisher. The majority of the times I failed ghosting were because of Magnet Fisher. Sam Fisher is a tad too eager to stick onto objects and too reluctant to unstick. Fucking annoying.
