The Great Seducer - it's kinda fun for the first two episodes while it's focused on the three friends and then it becomes just actually terrible
Murphy's Law of Love - it starts fun, gets draggy, and then gets annoying. It's not as bad as The Great Seducer but it's nothing special
One Smile is Very Alluring - this movie and the drama Love O2O are based on the same book and share much of the same content, the movie is fine but personally I think the drama is much better, if only because the drama platform gave more time to flesh out characters and explore storylines, and because the chemistry was better between characters.
