It isn't pointless, if we keep in mind that what constitutes a "mistake" (and what constitutes "innovation") depends upon the rules the author was supposed to be abiding by. Otherwise, we risk convicting a man when he'd no way of knowing what he was doing was wrong, since the law hadn't been written yet.
The man was born in 1892. That should make his work far more comparable to that of H.G.Wells (born in 1886) and EE "Doc" Smith (born in 1890) than to George RR Martin (born in 1948). The literary rules these guys followed were those of a different age than our own, and they were the ones forging many of the standards of novels today.
Thus, I think the original question Reaper asks is rather flawed. It is quite reasonable to question whether Tolkien is a particularly riveting read to today's readers, and discuss why and why not. It is not nearly as reasonable to try to call the differences between what he does and what modern authors do "mistakes".
