When people use the word "like" they usually mean they actually have a fair amount of regard for something, rather than using the word as opposed to "dislike". When I saw Tomb Raider (the 2001 film), it wasn't quite as bad as I thought it would be, it was watchable but very forgettable, but in a conversation about films I wouldn't say "I like Tomb Raider". Or celery, I can eat it (some people can't stand it), but I don't actually "like" celery.
