Okay so, many people gave this movie a one-star rating because mostly the movie itself was confusing and very VERY narrative that it felt so boring to watch.
HOWEVER, I say that this movie is one of the 𝐛𝐞𝐬𝐭 𝐩𝐬𝐲𝐜𝐡𝐨𝐥𝐨𝐠𝐢𝐜𝐚𝐥 𝐦𝐨𝐯𝐢𝐞𝐬 𝐞𝐯𝐞𝐫 𝐭𝐨 𝐛𝐞 𝐦𝐚𝐝𝐞. Why? You see 𝐋𝐮𝐜𝐲 𝐢𝐬 𝐨𝐧𝐥𝐲 𝐚 𝐟𝐢𝐠𝐦𝐞𝐧𝐭 𝐨𝐟 𝐉𝐚𝐤𝐞'𝐬 𝐢𝐦𝐚𝐠𝐢𝐧𝐚𝐭𝐢𝐨𝐧. She is someone Jake met when he was younger, but he never actually asked for her number, so they were never a couple. It might be 'Lucy' who's narrating the movie, but that's really Jake as he imagines what might have happened if they were together. As the title of the movie, 𝐋𝐮𝐜𝐲 𝐭𝐡𝐢𝐧𝐤𝐬 𝐨𝐟 𝐞𝐧𝐝𝐢𝐧𝐠 𝐭𝐡𝐢𝐧𝐠𝐬, 𝐛𝐮𝐭 𝐚𝐜𝐭𝐮𝐚𝐥𝐥𝐲, 𝐛𝐞𝐜𝐚𝐮𝐬𝐞 𝐬𝐡𝐞 𝐢𝐬 𝐨𝐧𝐥𝐲 𝐚𝐧 𝐢𝐦𝐚𝐠𝐢𝐧𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐉𝐚𝐤𝐞, 𝐢𝐭 𝐰𝐚𝐬 𝐉𝐚𝐤𝐞 𝐭𝐡𝐢𝐧𝐤𝐢𝐧𝐠 𝐨𝐟 𝐞𝐧𝐝𝐢𝐧𝐠 𝐭𝐡𝐢𝐧𝐠𝐬 (𝐰𝐡𝐢𝐜𝐡 𝐢𝐬 𝐤𝐢𝐥𝐥𝐢𝐧𝐠 𝐡𝐢𝐦𝐬𝐞𝐥𝐟).

If only people ever know the full truth and understanding about this psychological movie, I bet they wouldn't be thinking that they wasted their time watching this movie.
