Rockland is your typical shopping mall. It has got the stores you would expect to find in most malls. You can expect a decent amount of higher-end stores here like BCBG and Michael Kors so this is probably not the place to come if you are on a budget or looking to score a deal. The food court is as good as any other shopping mall.
As others have pointed out the location could be better. If you are trying to come or go during rush hour you can expect some traffic frustrations. If I do come here I try to come on a weekend morning when there is no traffic so I can get in and out without hassle.
