They ask for your personal information to sign up. In order to watch movies online for free, they require you to give them your credit card information. This is very suspicious.
They say the first month is free, but you need to give them your credit card info to sign up. So they can steal your identity and charge your card. They probably don't let you cancel the membership and then they charge you a ridiculous fee. They don't even tell you how much it will cost after the first month.
