Any flag that cucks itself by having the union jack on it. Looking at you Oz/NZ… It’s time to move on.

Morocco has the worst colour scheme. Low contrast makes the star disappear when viewing from far away.

Four bars is already too many, adding a big red line down the middle is not helping, and tbh if you took away the star it’d at least be symmetrical.

If your flag is gonna be busy, at least be creative and put like a dragon or something on it.

Sorry CAR.

All the tricolor ones. At least put something there ffs, Serbia and Slovakia did and it’s still not great but much better.

Wales.
There’s something seriously wrong with that dragon.
It’s got a tail as its tongue, a hook-nose, fluffy ears,
an air cushion frontal neck, a fishnet back neck
and a look so annoyed that
if flag dragons could talk I’d swear it would say
“Don’t look at me, my mom put me up for this”.

Imo good contenders are Nicaragua and El Salvador for being so incredibly generic. At least other Central American countries have more unique designs.
