“Good” depends on what you value, but the short answer is: **many people consider Obama a consequential and often effective president, while others think he fell short or made major mistakes.**

A fair summary:

### Major arguments that he was a good president
- **Affordable Care Act**: Expanded health insurance coverage to millions, even though it remained controversial.
- **Economic recovery**: He took office during the 2008–09 financial crisis; supporters credit his administration with helping stabilize the economy and reduce unemployment over time.
- **Killing of Osama bin Laden**: Seen as a major national security success.
- **Diplomacy**: Supporters point to the Iran nuclear deal and the reopening of relations with Cuba.
- **Social progress**: His presidency coincided with major cultural and legal shifts, including support for same-sex marriage.

### Major criticisms
- **Partisanship and gridlock**: He promised to reduce division, but polarization remained intense and arguably worsened.
- **Foreign policy**: Critics point to Libya, Syria, drone strikes, and the rise of ISIS as major failures or moral problems.
- **ACA flaws**: Opponents saw Obamacare as government overreach and criticized rising costs or market disruptions in some areas.
- **Race relations**: Some critics argue tensions worsened during his presidency, though supporters dispute that he caused this.
- **Limited structural change**: From the left, some say he was too cautious on banking reform, immigration, and inequality.

### Historical reputation
Among **presidential historians**, Obama is usually ranked **above average to very good**, though not typically at the very top tier like Lincoln or FDR. Among the public, views are much more partisan.

### Bottom line
If your standard is **stability, competence, major domestic reform, and personal integrity**, many would say **yes, he was a good president**.  
If your standard is **overcoming division, avoiding foreign policy missteps, or delivering deeper structural change**, you may say **no** or **mixed**.

If you want, I can also give you:
1. a **neutral report card by issue**, or  
2. the **best case and worst case** for Obama in a more debate-style format.
