If the reaction on Twitter to last night's early screenings is any indicator, then The Walt Disney Company (DIS -0.27%) and Marvel Studios need to get busy greenlighting a sequel to Captain America: The Winter Soldier. Accelerating the inevitable tie-in to Marvel's Agents of S.H.I.E.L.D. might also be s good idea.

But don't take my word for it. See for yourself:

ComicBook.com tends to document fan reaction to these sorts of early screenings. My sense from their findings this go-around is that audiences like Captain America: The Winter Soldier as much or more than they did Iron Man 3, which earned a coveted "A" CinemaScore.

Marvel Studios' superpower = connecting with audiences
Don't know the CinemaScore? I can't blame you. Designed more for studio executives than Wall Street analysts, the CinemaScore is an exit poll whereby audience members grade the film they just saw from "A" to "F". Movies that grade well tend to enjoy strong word of mouth and higher overall box office returns.

You might even say the CinemaScore is the most important indicator of box office success or failure. Twitter buzz for last night's early screening of Captain America: The Winter Soldier suggests a particularly good CinemaScore is in order.

Of course, no one in Hollywood will be surprised if the film performs well. Marvel Studios has a remarkable record of making crowd-pleasing epics. Phase 2 films Iron Man 3 and Thor: The Dark World fared especially well at the box office:

Notably, both Iron Man 2 and Iron Man 3 earned an "A" CinemaScore, while Thor: The Dark World improved on the B+ its predecessor enjoyed. All three films earned at least $600 million in worldwide grosses. Don't be surprised if Captain America: The Winter Soldier -- which opens on April 4 and doesn't face stiff competition for nearly a month -- pulls that much or more.
