Definite confirm. I'll take MGS2's convoluted plot as well as the second Matrix over this self-indulgent banality. And the drawn out cut-scenes and uninteresting, weaker plot both in the script and presentation (compared to 1 & 3) which overcompensated for the series supposed complexity by making it almost pedestrian. Also, way too didactic, even by its own standards; like they really wanted to make sure everyone from a fool to a kid understood the message and got the point.
Boss fights were too similar as well, the last one was a letdown, some of the gameplay mechanics were underused, the arms dealer and his monkey seemed out of place within the MGS universe and made it look like Kojima was trying too hard.
Overall, no where near the emotional and intellectual impact than the rest of the series.
