As far as low-budget sequels go, Beneath the Planet of the Apes really isn't bad. They don't try to recycle all the same ideas the original had, but actually expand upon the Ape universe. You will have to suspend your level of disbelief a little (especially at the beginning which has several dumb moments), but as the movie goes on, tension starts building and the plot gets weirder and weirder until it all (literally) explodes with a very bold ending. In the end, I think Beneath is a worthy sequel to a classic sci fi film.
