Unit 6: Writing a critical review

Look at this example:

A study by Daniels (1998) found that group exercise was more effective than a control (n=21) in significantly reducing anxiety symptoms among 22 middle-aged men. The participants were randomly assigned to groups and effects were maintained at 6 month follow-up. Beck (2005) reported that anxiety symptoms decreased in a group of 42 middle-aged men and women in comparison to a control. No follow-up measures were taken.

What is the problem with this as a piece of critical writing?
