sure, but you provided extremely bad way of solving a tiny issue, which you could solve literally by just blocking said users and not seeing their comments again. Most long comments are not just reviews posted as comments, but longer chats and analysis of specific aspects of the show. So what you want to do is limit everyone's expression because on a few users (in the scale of the whole website) who posts their comments even tho in your opinion these should be posted as reviews.
I'd totally agree with this sentiment if there weren't a limit on the number of users you could block and if the functionality of blocking were improved.
Also, whether the long comments are or aren't reviews, I don't think the comments section is the right place for them. Limiting the word count on comments doesn't really limit everyone's expression because they can still leave these long comments elsewhere - e.g. the reviews, discussions, feeds, or even the forums right? I also think good analysis and thoughtful responses get buried in the comment section, especially on popular and currently airing shows.
If we're talking about limiting people's expression, I think the comments section already does that. If you have an unpopular opinion and share it in the comments section you can get bombarded with attacks. It's the most accessible place to talk about a show but it's also the most prone to abuse. I've even reported users for name-calling and attacking each other only to come back weeks later and find the comments still there. I personally avoid participating in the comments section because of these reasons, but I'd be astonished if there was anyone who cared that my expression was being limited or other users like me.
Honestly, I'm not in favor of limiting the word count for comments. I think introducing a "see more" feature, as suggested by burhaa aadmi, would be a sufficient solution. Improving the block function and allowing users to delete replies to their comments would also contribute to solving this problem and many others, at least from my limited perspective.
