As a Law student, I'd say if you like reading (lots of independent research and reading required), don't mind the heavy work load and find it somewhat interesting - you should go for it.
It will certainly be rewarding for you when you graduate, but also look out for what style of teaching the university offers.
I'm currently at the University of York and their Law School uses a process known as Problem-Based Learning (PBL) and we're all put into student law firms. By actively learning this way, you gain skills which you'd need most when working as a lawyer. I'd most certainly recommend looking at York because of the engagement you get as a learner - also you're not alone, you have a law firm and 'junior partners' (year two/ year three law students) to support you besides the professors etc.
Make sure that when you're looking at Law degrees, that they have modules on things you would consider interesting, i.e. Roman Law as a very limited number of universities offer this.
Best of luck!
