So is pretty much every movie, mate. The point is to make it believable as you possibly can, without tipping over into farce. You can believe that an experienced fighter can beat an inexperienced one. Thats not an issue. The issue, for me anyway, usually comes when they take a hit. Thats usually when I start blowing big watery farts at the screen. See also small women beating up massive built dudes. Like The Woman King, seeing 50something Viola Davis taking haymakers from 25 year old heavy weight like they are nothing. Each punch enough to knock just about anyone on the planet out cold.

John Wick is another one. The gun play and stuff is fun, but as a tactical exercise, John Wick regularly gives up good cover for more sensational action shots that should have gotten him killed a million times over. The trick is making it fun. If you can do that, the audience forgives any bullshit. If you cant make it fun, the audience will nitpick it to fuck.
