Yeah, I was really impressed with how well they transitioned Isaac from a silent protagonist to a speaking character. I was a little worried about how that was going to turn out.
But my gosh. That eye-machine scene was probably the most intense thing I've ever had to do in any video game. As soon as I realized what it wanted me to do I was spazzing out.
I didn't really see it as a game ruiner though, I thought it was a pretty interesting twist. Call me crazy.
