Which movie is the biggest hit of 2010?

It's difficult to definitively say which movie was the "biggest hit" of 2010 without specifying which metric you're interested in. Here's why:

* Box Office Gross: "Toy Story 3" was the highest-grossing film of 2010 worldwide.

* Critical Acclaim: While "Toy Story 3" was a critical darling, "Inception" might be considered a more acclaimed movie by some critics and audiences.

* Cultural Impact: "The Social Network" arguably had a more significant cultural impact, sparking discussions about social media and its influence.

* Other Metrics: You could also consider things like audience satisfaction, awards, or even social media buzz.

Ultimately, the "biggest hit" is subjective and depends on what criteria you value most.
