HI Mrityunjay, 
List<BlogWrapper> blogObj = ( List<BlogWrapper>)JSON.deserialize(res,  List<BlogWrapper>.class);
       System.debug('Response- ' + blogObj[0].id);
        System.debug('Response- ' + blogObj[0].userId);
        System.debug('Response- ' + blogObj[0].title);
        System.debug('Response- ' + blogObj[0].body);
        //return blogObj;
You need to use array of the blogObj to debug. I tried this in my org and it works.

Hope this helps you. Please mark this answer as best so that others facing the same issue will find this information useful. Thank you
