I'd like to search for lists that contain maximum number of movies favourited by me, normalized by total number of checked (by me) movies in that list. So the formula of "list compatibility rating" could be:
R = (F / C+10)
R - list compatibility rating
F - number of favourited movies in the list
C - number of checked movies in the list
+10 - normalizing summand

I think this feature of recommended lists would be a great companion to existing movie recommendations.

I don't always want to tell the world I just checked a movie, whether it's because it's a movie I have already seen ages ago and just remembered to check it, or simply because I don't want to spam my Facebook / Twitter with a 100 checks of shorts.

It'd be nice to have a way to check a movie without posting it to linked social networks.

Not that I don't like it but it seems to me a bit out of place, like using an old radio as main icon for www.icheckoperas.com. A film camera, just an example, would feel more appropriate.

By adding this feature, other people can filter lists on services they use (eg NETFLIX UK)
You attract more users.
because the searches on Netflix are rubbish, everyone wins.

Great site. I have a suggestion. You should somehow show how many
movies a person has added to the website (how many IMDB links added i guess). It would probably generate competition - movie fans can be very competitive and love the attention :) Just a thought

Would be nice if the stats were more detailed.

e.g:

Checks: 1500
Official: 500
Movies: 1200
Tv episodes: 300
Rank: #6100
Rank title: Actor

I know that checks in eps from tv series does not affect the official rank,
but affects the total number of checks, masking the true number, this is the reason why I dont check eps,
but I want to. So, it would be great if the stats were more detailed.

that way I'll always know the answer to: "how many movies have you seen?"

Because many of us don't live in English speaking countries so most of the time it is not English titles that we see around.

Now that IMDb removed their decade lists, iCM should fill the gap by having its own decade lists based on favorite/check ratio.

On Last.fm they have a dynamic screensaver download where your screensaver is a selection of album art based on what you listen to. I think if it could be done here with the film posters (maybe with loved films getting a priority) it could be a cool secondary feature.

Currently a movie's INFO tab includes a display of all official lists which include the film. There is also a link to show all lists (official and personal) that include the movie.

New feature: I would like to see, in addition to the official lists, if the film is included in any of the lists that have been added to the "watchlist". These lists would be automatically displayed below the official lists. This would let the user quickly see if the movie is part of a list that interests them.

We have signatures for official lists that display our progress on the list, but I think it would be cool if we also had signatures for personal lists.

There are probably too many lists to generate a signature for every list for every user, but maybe you can allow each user to select up to 10 personal lists, and then generate signatures just for those lists.

Like on the "myanimelist" forum, the total length of all views is shown, based on the length it says on the IMDb page for every movie, added up.

Now we see:

You vs. xxx:
1347 - 1005 (checks)
and then compares each of the lists and shows who wins.

My suggestion is also show the total number of lists won and lost.

e.g:

You vs. xxx:
1347 - 1005
80 - 40 - 13 ties

Give the possibility to display our lists on dashboard at the way we want (custom or recent), same as favorite and owned.

Add to settings (on Misc) this option:

Display most recent list on dashboard (instead of custom ordering)

When opening a movies page there is a tab to check what lists it is in, iMC, personal or both.
A nice feature would be the possibility to filter that lists list on lists that I have marked as favorite or watchlist.

I would like to see a hot link to metacritic.com along with the imdb.com on the movie pages. if imdb is the encyclopedia, metacritic is the bible of movies. And with very reasonable reviews across all the web.

I think it would be great to have the possibility to choose which of your friends activities you want to see. This can be very useful especially for those who have many friends. In my case, sometimes I receive so many notifications, that I have difficulty to see what are my closest friends (in cinematic taste) doing.

Pages with all their movies on. It would be cool not to have to go onto IMDB to find an actors filmography, and which ones I've seen etc.
Also, top 10 actor list?
