The rotten_tomatoes dataset of movie reviews contains some reviews in Spanish 
Hi @puzzler10, thanks for reporting.

Please note this dataset is not hosted on Hugging Face Hub. See: 
https://github.com/huggingface/datasets/blob/c8f914473b041833fd47178fa4373cdcb56ac522/datasets/rotten_tomatoes/rotten_tomatoes.py#L42

If there are issues with the source data of a dataset, you should contact the data owners/creators instead. In the homepage associated with this dataset (http://www.cs.cornell.edu/people/pabo/movie-review-data/), you can find the authors of the dataset and how to contact them:
> If you have any questions or comments regarding this site, please send email to Bo Pang or Lillian Lee.

P.S.: Please also note that the example you gave of non-English review is in Portuguese (not Spanish). ;) Maybe best to just put a quick sentence in the dataset description that highlights this? 
## Describe the bug
See title. I don't think this is intentional and they probably should be removed. If they stay the dataset description should be at least updated to make it clear to the user. 

## Steps to reproduce the bug
Go to the [dataset viewer](https://huggingface.co/datasets/viewer/?dataset=rotten_tomatoes) for the dataset, set the offset to 4160 for the train dataset, and scroll through the results. I found ones at index 4166 and 4173. There's others too (e.g. index 2888) but those two are easy to find like that. 

## Expected results
English movie reviews only. 

## Actual results
Example of a Spanish movie review (4173): 
> "É uma pena que , mais tarde , o próprio filme abandone o tom de paródia e passe a utilizar os mesmos clichês que havia satirizado "
