GANGSTER SQUAD IS AMAZING <33 There's Ryan Gosling & Emma Stone so enough said :p But seriously if you're into gangster movies & like the 50s era, you'll love it :)
Out of this list I've seen the Way way back too and it was a lot of fun, I loved it :) But yeah it's very different from GS :D

Haven't watched any of these but this one sounds good. Like Aline said if Ryan Gosling and Emma Stone are in the movie than I bet is great.

I've only seem this one.
It was alright. It honestly isn't as scary as everyone made it out to be lol but it's worth a one time watch.

I've only seen this is 40 but I love it<33
Sadie is basically you Holly so enough said.

Gangstar Squad sounds great, getting it for my birthday yay! :D

Oh yeah i forgot to say that I've seen all of these except for The Purge, Gangster Squad & The Way Way Back.

Hahaha Bee, I KNOW! I saw This Is 40 in theaters and i was GEEKING OUT over Sadie!

lol now you've got me hunting down Sadie gifs on Tumblr. There goes my productivity for the day!

The only one I've seen

^ That! I've seen Gangster Squad only for my babies Emma/Ryan but it was soooo boring!
