This is an excellent video. Truly, it is. The fact is, I have never played this game, or any of the Bioshock games, but I am familiar with them and do enjoy watching gameplay videos. And since I know it's unlikely I'll ever play Inifinite, tonight I decided to watch the ending, just because I can. And I did, and from that I found your video. Here's the thing: even though I didn't play the game or really know anything about the story or characters, I completely understood the ending, and my thoughts match up to your explanation almost exactly. It's not an airtight ending. That's easy to see. But it does work to some extent. So it baffles me that anyone could be confused by the ending. It's all laid out, right there. You don't even need to have witnessed the finger thing from earlier on in the game, to clue in on the fact that, hey, Elizabeth is Anne, Booker's daughter. The only truly messed up thing is the baptism and how somehow that causes Booker to become Comstock. I get it, but I don't like it. Maybe it's because I'm a writer and also a lover of speculative and experimental fiction; my brain is wired to just accept weird stuff, like Inifnite's ultimate conclusion. I've read vaguer things! And yeah, I'm also familiar with the multiverse theory. But in this day and age, who isn't? What with how many films and television shows have featured it to some extent.
