your op is very confusing. what negative reviews have you heard about law? about a law degree or about the pursuit of a legal career?
law isn't a risky degree. there's tonnes of things you can do with a law degree, some of which have nothing to do with law and i would say no more risky than the other three you mentioned. or do you mean you would pursue another profession with a non-law degree? is the only value in an LLB to you a TC when you're 22?
those other degrees might be less work; you might be right there if that's what's putting you off law. bearing in mind, there's 100+ LLBs in the UK and they aren't all the same. i know a flatmate last year and i both studied law, but at different unis. her degree was vastly different to mine. i also haven't studied at sussex or swansea so who knows what their programmes are like. if you're seeing negative reviews, it's coming from a subjective place. i would study law till i pass away if i could, but that's just my perspective. if your 'negative review' is about the pursuit of a legal career with an LLB tho and you're not willing to work in the industry without a TC then i would say do something else. it doesn't seem you're interested enough to do three years LLB.
