be nothing to shout about

To be not especially remarkable or noteworthy; to be rather dull, mediocre, uninteresting, or unimportant. A: "Have you eaten in that new sushi restaurant yet?" B: "Yeah, I went there last week. It was OK, but it's nothing to shout about." His performance has been nothing to shout about so far. To be honest, we were expecting much more from him when we recruited him. Bill said that show was nothing to shout about, but I actually think it's pretty entertaining.
