Alexander Stegmaier is okay but not always strong

I watched Mutt (2023) and Alexander Stegmaier was one of the parts I kept noticing. Some parts are good, but other parts feel normal and not very fresh. There are good moments, especially when the scene is quiet. The performance is okay for the movie, but sometimes it feels a little flat. I can understand what the actor wants to do, but not every scene is strong. I remember both the good parts and the parts that did not work so well.
