It will certainly be interesting to see how this film turns out given the oft-cited point that Link does not traditionally speak during the games (though I think he did in the CD-i games).
It's also worth noting that video game based movies rarely do well. I'm not sure what the general consensus was on the Illumination Mario movie, so maybe people are more optimistic for this movie if they liked that one. Personally, I didn't love the Mario movie, so I'm still a little uncertain of the potential quality of this movie.
I certainly hope this movie does well, though. Then we can finally get the Chibi-Robo movie we've all been waiting for.
