Seems to like power rangers I think. 

Knows I like Power Rangers and Super Sentai, but Power Rangers has better music.

Is a sentai fan

Doesn't know Power Rangers has better music than Super Sentai.

Knows that Power Rangers are superior, good.

Acknowledges that Power Rangers definitely has it's advantages over Sentai, but should know that Power Rangers sometimes has had disadvantages over Sentai plot-wise (Some Power Rangers seasons ended up worse than their Sentai equivalents, like the transition from Carranger to Turbo).

Doesn't realize that sentai is a category and power Rangers is part of that genre

Doesn't know I meant Sentai as in Super Sentai, which is what the genre is named after, and includes the likes of Sailor Moon and Science Ninja Team Gatchaman.
