You're acting like the typical internet fan.
The type of cat that obsesses over a show....pores over every minor detail....discusses theories, does re-watches etc....and that's most of this thread....but it's damn near impossible to surprise someone like you.
And that's fine. But Angela literally said "you're not the real Elliot" in season 1.
The average person would see the revelation in the finale as a well earned pay off.
You see it as cliched and would rather they introduce sci-fi in the last 2 eps of the entire series, solely because it's unpredictable. But it's only unpredictable to you because like I said....it's damn near impossible to surprise you. The only way that happens, is to introduce something that wasn't even hinted at, at any point in the series.
We went through the same thing in season 2. 99.99% of the people watching this show didn't know he was in jail. Go on forums, or Reddit, or social media and it's
"how predictable." You cannot surprise people like that. You'll fukk around and wind up in "Lost" territory trying to cater to them.
