I understand some here are critical of Battle of The Ministry (and that's perfectly fair), but it generally seems to be highly regarded by the general public and is seen as one of the park's marque attractions.
I don't think this is that big of a deal, since the amount of guests who visit both Universal Hollywood and Orlando is somewhat negligible. Orlando's version also stands apart from actually being "complete", and having more attractions and offerings.
I feel like these lower ratings are largely a result of operational issues, since Battle at The Ministry and Mine-Cart Madness suffer from the worst downtime in the park, and SNW has had some other technical problems at times.
