Dwarf is spelt wrong.

Also the primates one is a bit off, as monkeys feels too generic, a particular breed of monkey would be better.

No idea what "pop" is doing in that group -- and neither does google. Unless you mean the game, which does not fit the hint or the category. It's like saying Run is a type of chicken because of the film title.

Annoying quiz, but wanna help you do better next time.

First off, the groups are super obvious. Not WHAT they are... but four animals with "S" on the end and nothing else has an "S"... four short words which probably combine with other words... four character races... there's no overlap among the sets (exception: actually "Giant" could be in the fantasy set, but clearly isn't if someone knows Tolkien; and humanS could have been in the primate group). I got the groups first guess in a few seconds. Try putting in red herrings or at least including things that look like they might go together.

Second: the Tolkien group is too specific in what you want. Yeah they're all in Fellowship of the Ring, but they're also all in The Hobbit, Two Towers, and Return of the King, not to mention any generic fantasy setting which imports hobbits (most of them don't, preferring terms like "halfling" or "kender", but there's hobbits in Fighting Fantasy for example), and they're all playable races in MERP and (I think) LOTRO. At the very least you should be accepting "tolkien", "race" and "fantasy" as links.

Having "giant" and "red" (which are types of panda/followed by panda) with "car" and "pop" (which are products called panda, or preceded by panda) is too far from a real group in my view - it needs to be either preceded, followed, types, or products.

The movies group is OK but very obscure from my POV. But that might just be because I don't know movies.

To make it better, you could for instance have included more fantasy races. Put in "orc" or "troll" for instance. Then move some of them to other groups. e.g. you could have had an animals group with a "dwarf" species (hamster, rabbit...) or put "troll" in an internet group, or "man" (Tolkien's term) in a word group (things which can come after "fire" or "post" or before "kind", etc). Or put "human" in the primates group along with three others. Make a couple of them obscure species we're less likely to have heard of, or something like "Neanderthal" which could be in the fantasy or the movie group. Then find a film which goes in one of the other groups and build the film group around that (including or excluding it). For example "gorillas" is the first word of "Gorillas in the Mist" and "Gremlins" is a movie title but also a fantasy race.

I don’t think monkeys are primates.
Had not heard of Pop panda.
