I love wings so they get a pass.
I agree with Raoul Duke above about calamari.
It can be very good, or not that great, depending on the place.
I also think calamari is the only seafood that makes sense as an appetizer and others are more fitting in meals only.
Other appetizers I've never really been big on understanding are loaded fries, because so many people are already getting fries or a baked potato with their meal.
Also mozzarella sticks...
