This is the 955th most frequent Japanese word.
久しぶり
"久しぶり" means "long time no see" or "after a long time."
Here, '久しぶり' is used as a standalone exclamation to greet someone the speaker hasn't seen for some time.
久しぶりですね！
It's been a while, hasn't it!
'久しぶり' in this sentence conveys that much time has passed since the last occurrence of the action (watching this movie).
この映画を見るのは久しぶりだ。
It's been a long time since I last watched this movie.
In this case, '久しぶり' expresses the idea of doing something (meeting a friend) after not having done it for a considerable duration.
