SPOILERS I think Soundwave was totally done with justice. When a character is portrayed just like his G1 version, I feel very happy. And with Soundwave being my favorite character, I think the writers wrote him perfectly. Sure he got less screen time but his role in the movie was cool. We got to see his face, which was really important. He got his monotone emotionless voice. Even though there was no interaction between him and megs, you can tell that his loyalty lies with megs. And also the fact that he released Ravage was an awesome G1 touch. I love that it is possible he can have a pivotal role in the 3rd one.
