Okay...
First, 'Gigli' is definitely going on. As I mentioned, it needs some fresh stuff and that is a major keeper! Nice Scott!
As far as the others go, to each their own. 'Father of the Bride' is definitely an acquired taste, but just not good enough. 'Island of Doctor Moreau' has good actors and some good effects and make-up, but that doesn't mean it's a good movie. The Mummy is entertaining, but cliche and hard to take unless you are watching it on cable. Some of these are bad theater movies, but great for cable movies.
Vator, I liked Independence Day as well and for some reason I'm not seeing it on the list. So, I can't comment other than I also agree, if it is on the list, that it is good enough to have it removed.
Howard the Duck is a cult movie and a comic movie. While it may suck, it has enough redeeming qualities and closet fans that it will stay off.
I forgot to mention that these have to be movies that more than one person has seen in order to verify the suckiness. So unfortunately, I cannot agree with 'Party Monster' SPIDERLEGS, and I hope to never be able to verify that it is bad...
