You have to "Sign Up" before you can login. I would have done it, but they wanted my birthdate. That is something I'm not going to give for something like this. I'm not that interested in reviewing or discussing movies.
Yeah, I'm annoyed at the "useless" services that keep wanting your birthdate, not the least because it's still the backbone of tons of extremely important stuff. "For your security, what's your birthdate?" (??!) You might almost want to say "it's on my facebook page." The other one is medical. Because they don't want million dollar lawsuits when two John Smiths show up for treatment, they always ask "so your birthdate is...?"
Except for weird cases, those places don't need birthdates. The only fuzzy one is when you want to look at some NSFW stuff and they're required to ask *something* from the 2257 rules. So just give them Jan 2 19xx the year *after* you were born, aka you're plenty old enough, and in the twilight zone case if it ever matters, you/counsel says, "oh I'm sorry, I'm OLDER than I told you."
