I honestly agree with you, i love this franchise, but i find this one is quite annoying, so... Here's my problem, well... Um.. As you can see.. Every time you finish mission you have to call helicopter & on & on & on & on - ugh lol. And chapter 2 feels like scrambled because i have to do some "important" side ops.. Errr... Aren't they suppose to be part of main missions? And why did they repeat few old missions from chapter 1 with challenge version (extreme, substance, total stealth) on chapter 2? Boss fight, no, i don't like it, nothing epic fight for me... Quiet, *flips table*, i finished the game, however my completion is only 39%, i don't care about side ops. xD(Even Motherbase... I know there are everything out there... And i hate progress!).
One more thing. {DO NOT READ, IF YOU HAVEN'T FINISHED THE GAME YET. SPOILER}
True ending... Wow! Great plot-twist, we've been playing as medic a whole time, not a real Big Boss, his Phantom. No wonder why real Big Boss appeared again in Metal Gear 2: Solid Snake. Imagine you had glitch/bug triggered that goes straight to the true ending, you would've been desperate as f@#k. And yeah, episode 51 is very sadly not indcluded due to budget issue, unless only for collector's can watch the concept.
