Users criticize the uninteresting, muddled story with weak script, predictable plot, and slow pace. Comedy flops in a lifeless, boring film, with poor chemistry between leads despite real-life romance. Characters are unlikeable, dialogue absurd (e.g., genital debates), and cameos highlight the rest’s flaws. Offensive elements like caricatured disabilities and conversion tropes offend, while the script’s dire quality matches on-screen execution, making it a notorious flop that sank careers.
