I have to say that IMBD is one of the top visited sites that I visit everyday.
Since it's free I can't and shouldn't complain but sometimes the search can be very bitchy!

The only thing that I regret not having anymore which was called;
"THE CROSS REFERENCE CONTEXT SEARCH" "Key Word search" or something like that..
The OLD SITE HAD IT! You would enter one or more key words and it would perform a special search to bring you titles that the plot has something to do with the words of your choice... And this was a loopy search where you could change the parameters on the go.. So you cold type; bride, horse ride, car accident, submarine, Chines man..."(you get the idea) and it would bring you all the titles that got those elements in them and add extra key words to the pot that the tiles might have in them.. So you can add and remove the key words as you conduct your search... IT WAS GREATEST & MOST USEFUL TOOL that I've ever came across to AND IT IS GONE! And that frankly makes me sad...
