SB wants to watch the avengers

I heard that the movie avengers is really grate because some of my friends already watched it but i'm still thinking if i can watch it by this week or next week. i don't not but i'm hoping to have a free schedule since i'm busy in the school i don't have enough time to watch for it so i'm planning to Watch The Avengers Online FREE this coming saturday together with my boyfriend. But i think it's much nicer to watch it on a big screen right? Anyway tickets are almost sold out so i really need to know my schedule asap!
