In regards to Audition, Ringu and Nightbreed, I think Ringu is the better, but for the other two, people tend to polarize (like/hate), and I don't have a strong opinion in them. So I'm cool with results.
Arachnophobia - Nice debate going on. Consider this: director Frank Mashall expertly shot scenes to fully exploit fear of spiders - recall the scene of spiders coming out of the faucets; the spider on the table that keeps facing and moving with every move of the actor; spiders bursting from the pulsating spider sac. Very effective creepiness & exploitation of fear. For those who consider it might not a good enough film, take into account the 91% Critic rating at RT (34 critics).
