CGI can go a long way, but it won't ever fully replicate human movement/likeness.
Films that use CGI excessively are invariably awful (insert Sam Worthington film here).
I think it can be fantastic when used in animations, but when it comes to a live action film, Christopher Nolan's approach is my favourite. If you can do it for real, do it for real, but use the ever-improving CGI to fill in the gaps.
