PSA: it is ok to want to be visually attracted to your partner
I'm not sure why it is considered "shallow" to want to be attracted to the person you marry. Obviously, most of us are in the average range of beauty, and so will attract people of average beauty (unless you have something exceptional about you, like extreme wealth, power, or insane levels of personal charisma). Even so, it is not wrong to want to marry someone who is attractive to you.
Now, obviously Love is Blind is a reality tv show, so the contestants are going to be selected on a few traits, including some level of physical attractiveness. I've only seen a few episodes but no one on the show is outright hideous, and most people are above average, and also they are made up to be above average.
Even so, trying to fall in love with someone from a separate "pod" is absurd.
