A boring fight
Fist fight attempted to be a unique comedy that has a build up towards the main fight, and the results were just poor. Comedy is a hard genre to make specially that each viewer has different taste, but for this one its lame. The plot is predictable and boring (no surprise moments whatsoever). And the gag moments was just average or childish that was sometimes eye rolling. So coming to the main fight, it was lengthy but didn’t give anything special and it had stale taste.
To conclude, there are audiences who’ll love this kind of comedy which is raunchy or expected gag but it is not the level of comedy that will make you remember such a movie.
