Agreed. One of the only times I contributed to the board was on a thread discussing why time travel in Timecrimes[1] (superb movie!) was not consistent. Without spoiling it, we ended up discussing all sorts of alternate theories in an attempt to have it make sense.
Another cool thing is visiting the boards of interesting movies or shows that are still far out from release. You usually find details about estimated release date based on current progress and photos from production.
yep, time crimes was very good, i remember very good discussions also in The Prestige board regarding teleportation
btw TMDb just launched discussions yesterday so feel free to participate there, of course don't expect years of comments, but feel free to copy interesting topics you made from IMDb
