So, my thoughts after finishing the game again.
The writing during the final Illusive Man encounter is just... Not very good. Unless, of course, you're looking at it from the "TIM's finally gone over the deep end"-angle. Then it makes sense.
And any writer who puts in a floating magical space platform and then goes off about how you have a choice should just quit. The worst part is, I wouldn't have minded fucking vent god if he actually had some decent dialog. Instead he goes rambling about how Shepard being there changes everything and how shit shouldn't change. He was the one who pulled that floaty platform up there in the first place.
If he would've explained why, sure, why the fuck not, I could live with it. Instead it's like the creator of the Reapers has no clue what the fuck is happening around him. I honestly don't even understand people who say they like it, and I'm usually a pretty open-minded person. But this? It's bad, no matter how you spin it. I can understand BioWare wanting an ending that left things open a bit, that didn't answer everything or provide a happy ending with closure. That's an artistic choice. The way they presented it, however, is shit. The Catalyst does things but doesn't know why. If he was so fond of his "solution", he could've just let Shepard die. The themes people are saying were so "out of the left field" were present in a lot of ways during the game... Just way too subtle. And Javik, a character only a minority of people have, is the main supplier, too. No wonder people are pissed.
Here's my take. I don't want BioWare to change the ending completely. I can appreciate what they tried to do. But honestly, the discussions with TIM and, more importantly, the Catalyst need changing. The latter is a prime example of shitty writing, with the reasons I stated above. Just rewrite and re-record that shit. I honestly would've minded less if he told Shepard why he brought him there, instead of (with low EMS) asking him why he's there. Have him be somewhat coherent instead of rambling about chaos and order and synthesis and expecting the player and Shepard to understand it and make a choice. Unless BioWare, in their absolute brilliance, tried to make a play on the organic/synthetic duality by having the A.I. creator of the Reapers going senile.
Apologies if my sentences are a bit weirdly structured, but I'm tired and sick. :lol
