Let's not turn this into a Marina Sirtis bashing topic.
DS9 isn't for everyone.
Sirtis not liking it doesn't make her a lesser person.
No, it doesn't. The reason people find her remarks off-putting is because one would hope that she would be more professional in her comments about another Star Trek
series. She may not care for Deep Space 9
, but there are many people who are fans of both it and The Next Generation.
