Sonic the Hedgehog is a trite childrens film. Sonic looks better than he did in the first previews but it doesn’t help that he is annoying. Jim Carrey mugs for the camera and acts like a jackass for the running time. The only redeeming quality was James Marsden who has too much charisma for this movie. I am not a child, so I get that I am not the audience for this. However, when I can guess the lines of dialogue because the script is so predictable, you might need a rewrite. It’s not the worst movie, but it’s also not so bad that it’s entertaining.
