Season 15 received positive reviews, though many reviewers commented that while the episodes were generally enjoyable, they were of a lesser quality than those of the series' first decade. The general consensus is that this marked an improvement over the early teen seasons.
High Def Digest gave a rating of 4 stars, writing "The Simpsons' is one of only a handful of shows that I know I'm guaranteed to laugh out loud at least once an episode (usually more). Even though the cutting wit of the first decade lost its edge a bit, I still find 'The Simpsons' an extremely enjoyable way to spend my time. There aren't many things that are better than sitting down with a new season of 'The Simpsons' on Blu-ray and watching every episode back to back as fast as I possibly can. While the episodes sort of blend together, the humor is still there, and I still end up having quite a few genuine laughs". CraveOnline rated the season 8.5/10, noting "Some "Simpsons" fans gave up during a perceived rough patch around season 12, and boy have they missed out. Season 13 was a particular favorite of mine, but now we're over the hump on the DVD releases. Season 15 is kind of a sweet spot, because it's got some highlight episodes I love, but also plenty that I don't remember." DVDActive said "The Simpsons season 15 isn't one of the series' best, but I'm pretty sure it isn't one of the worst either". ScreenJabber gave a rating of 4 stars, writing "Imagine my surprise when I sat down to review Season 15...and realised that I had never seen most of its episodes. Imagine, then, my joy at being able to enjoy almost 22 episodes of factory-fresh Simpsons, even though they were made about a decade ago. And even though some of the cultural references are a little dated, there's still an awful lot to laugh at and enjoy here. As always, this season of The Simpsons features a stellar line-up of guest stars. And, as always, there are some standout episodes. All in all, a more than decent season of this long, long-running show." DIY wrote "While Season 15 of The Simpsons may not be golden from start to finish it has a higher great to soggy episode ratio than more recent seasons. In fact, there are some real gems amongst the 22 episodes". Boxofficebuz gave it 4 stars, and said "...Throw in flashback episode 'The Way We ,' Pie-Man antics in 'Simple Simpson' and a Catch Me If You Can spoof in 'Catch 'Em If You Can,' you have a solid, solid season. A definite uptick over the previous couple seasons". BubbleBlabber rated it 9.0 out of 10, and concluded "In terms of the content, Season 15 was a highly underrated season for The Simpsons and brought along a number of now well-known classics". DVDMg gave the season a B, and wrote "Should viewers expect greatness from Season 15 of The Simpsons? No, as the year comes with some mediocre shows. Still, it delivers a reasonable number of good episodes and seems worthwhile overall...S15 won't win over new fans, but it's usually fun".
