Yikes! I had a situation that started like this, but thankfully it was caught early. When I got my wisdom teeth removed they were impacted so they had to sedate me, and for a few minutes after I was supposed to be sedated I was "Still there" too and could hear the doctors but couldn't move, thankfully one of them caught it a few minutes in and gave me another dose or something so i ended up knocking out, but I remember how terrifying that was and this movie did a pretty good job conveying that feeling.

Side note that's also literally the highest I've ever been in my life after waking up.

But the movie has a couple issues, the main character to me just wasn't very likable, neither was his mother. Only Jessica Alba's character was likable until a point in the movie.

[spoiler]That all said, I think the movie was interesting enough before the twist. Then I just wasn't rooting for anyone anymore and waiting for the resolution. Probably could've done without that whole subplot all together and just made it about the actual event and it'd have been better.[/spoiler]
