Shotgun Wedding is a perfectly fine action comedy that knows exactly what it is and is more than happy to coast by on the solid amount of chuckles, nice backdrop and predictability of its plot. It never gets a big laugh but is still generally entertaining enough to avoid becoming boring or overly stale. It's the kind of film designed for streaming, in an inoffensive way.
Jennifer Lopez and Josh Duhamel work well enough together. Their chemistry is solid and they can keep things going on their rapport for the majority of the run time. Jennifer Coolidge gets the right amount of screen time so she can be a fun addition who stands out in every scene without becoming too much. She is pretty much the only other memorable person in the whole cast.
Jason Moore's direction is fine, helped by the tropical setting. There's only one memorable shot and everything else is competent with the classic tropes and jokes of an action comedy executed in a fun fashion. The best moments come from the rising body count and the way they are dispatched. Pinar Toprak's score has a lot of fun with it, ensuring the proceedings stay lighthearted.
