The writing is basic at it's best and after the only big reveal about the mysterious villain, half way into the film, Mission: Cross literally is devoid of any intriguing moments and the action too is quite generic to stand out. All it leaves is the two main leads to kick up the spark and the comic timing to salvage what's left but that just proves to be not enough. Even with the runtime of barely 100mins, the film gets boring and the half baked screenplay doesn't really offer anything to remember. Spoiler, the film does end on a note opening up for a sequel but there is hardly any interest left to care for it.
