It was pretty good, but many movies were that good. I picked Titanic specifically because it was broadly popular and culturally relevant.

as someone who had a DiCaprio lookalike in his middle school when it came out, who attracted ALL the girls' attention, and also as someone whose first date ever was to see Titanic

I begrudgingly have to admit it is a very good movie

Are you a woman? If not you can't really judge it since it was intended for women, not being the target audience doesn't mean it was bad, women absolutely loved the movie.
