I think the question is comparable to asking "do you like pizza?" I like
good sushi, and
good pizza. I have had bad versions of both, so I will never say "I love pizza" or "I love sushi" without qualifiers.
If you're a seafood lover, particularly a lover of Asian food, I'd think good sushi would be something you'd like. If you don't like Asian food in general, and/or you don't like seafood, then it's natural that you wouldn't like sushi, no matter how good it is.
To get good sushi, you need all of the following elements:
- Fresh ingredients - Freshly steamed rice, fresh sashimi-grade seafood, fresh vegetables (carrot, avocado, etc.).
- Good preparation - a sushi roll that's falling apart might still taste good, but it loses something when you can't eat it in one bite.
- Good quality associated elements - soy sauce, spicy mayo, fried wontons, pickled ginger, and "wasabi"...all or none can be used if desired. Note: "wasabi" is almost always ground horseradish that's dyed green in the States.
If you love seafood and Asian food, and you still don't like sushi, there's a good chance some or all of the above elements weren't done properly. The funny thing is, on a high level, I can say the same sort of thing about pizza or any other food. If you have something that's not prepared properly, or doesn't have good quality ingredients, then there's a good chance you won't like the sushi, pizza, steak, or whatever.
