>> Or did I misunderstand the MongonDB and it actually is so bloated by design?
Depending on the type of query and the way you designed your database schema MongoDB queries can be either more concise or (in your words) more bloated than SQL. You can't really say either one is more bloated than the other in terms of query syntax.
Personally, I generally prefer MongoDB queries over SQL, because it doesn't have a concept of joins, inner queries, temporary tables, etc, which usually translates to more but simpler queries. If the data model for your applications relies heavily on any of these features, maybe you shouldn't use MongoDB (or any other NoSQL database, for that matter).
