Manzanillo is the major port town along the Pacific Coast, not a luxury class tourist resort. As such, it has parts that feel quite industrial and it lacks the over abundance of tourist amenities found in some resort towns.
However, while it doesn't have the nightlife of Acapulco or the dozens of luxury class resorts of Cancun, that also means it doesn't have throngs of tourists or much crime either.
If you are looking for a more laid back location with a very Mexican feel, then Manzanillo is worth a visit.
