Sure, April showers bring May flowers -- but on Netflix, this month is bringing a lot of great movies you can watch after those flowers. The streamer just added some must-watch films, and Watch With Us has selected three of the very best for you to view this weekend. Leading the pack is Merrily We Roll Along, a filmed version of the Tony Award-winning musical revival starring Harry Potter's Daniel Radcliffe. You should also stream Atonement, an Oscar-winning World War II drama featuring Keira Knightley's best performance to date.
