No, sorry but portals would suck as a movie and here is why. The game is about puzzle solving aifh a little exploration on the side. With a movie you can't explore the world it is set in and I feel that wouldn't do the games justice. On top of that it would be like watching someone solve a puzzle, taking the fun out of that as well. With these two things in mind I feel it would leave the movie feeling empty and hollow. Now if they did it qthen th Ratman instead of Shell it would be a lot better. I say that Beacuse with him it is more of a running and being chased. It may not be amazing, but it could be okay.
