Law Review is definitely a mixed blessing. Thing is, 10 years into your career, it will still be on your resume or in your firm bio or whatever.
If you hate the process as much as you say, take the as a cue to what kind of law you might want to practice when you get out. You mentioned that you may not be into the big firm thing. That's probably a good call. The monotony of writing and editing required by law review is not unlike what you might expect to experience for your first few years of practice.
