  A critical look is taken at both positive and null evidence for the
$\Theta^+$ pentaquark. Potential problems with experiments will be discussed
and the question of what conclusion can be drawn from both the positive and the
null results is examined. First the question of existence of the $\Theta^+$
pentaquark is considered, followed by a discussion of new experiments that are
either planned or in progress to answer questions about its mass, width and
isospin. Finally, indirect evidence for the parity of the $\Theta^+$ is
examined, and suggestions for experiments to measure its parity directly are
given.
