Learn Turkish: Sen balık ye ve güzel bir film izle. - You, eat fish and watch a good movie.

This sentence joins two SOV phrases, but shares the same subject! It goes: Subject (Sen) + Object (balık) + Verb (ye) + and (ve) + Object (güzel bir film) + Verb (izle). You do not need to repeat the subject for the second half of the sentence.

Why don't the verbs ye and izle have any tense endings on them?

These verbs are in the command (imperative) form. When you give a direct instruction to one person (the informal "you"), you just use the bare root of the verb in Turkish. So, the dictionary verb yemek (to eat) becomes just ye, and izlemek (to watch) becomes izle.

Why is the word order güzel bir film instead of bir güzel film?

When you use an adjective (like güzel, meaning good) and the word bir (a/an) together before a noun, the adjective almost always comes first in Turkish. It literally reads as "good a movie", which is the standard pattern to remember.

If the command verbs already imply "you", do we need to include Sen at the beginning?

No, it is optional! Because the command form clearly tells us who is doing the action, Sen isn't strictly necessary. Including it here just adds a little emphasis, like saying "As for you, just eat fish and watch a good movie."
