It completely depends on your personal opinion.
No. It is one of the most important archaeological sites in the Americas, built BEFORE the Aztec civilization on 100 BC. On the 'related links section' you can see why it isn't overrated
no, south America is not a overrated travel destination.
Not in my eyes, but everyone has their own opinion. Just research Iceland and what you could do if you went there, then you decide if you would make the trip or not.

Dublin is an okay tourist destination. There are old british buildings (such as Trinity College Dublin) and good night life in Temple Bar. Grafton Street is good for shopping. If you're looking for a city break with good shopping, fun night life and history, Dublin is not overrated.
