What's the correct way of answering よくえいがをみますか。with "No, only sometimes."?

I am guessing it is incorrect to say いいえ、ときどきをみます。as いいえ should follow by
negatives instead of affirmatives?

How about いいえ、よくえいがをみません。ときどきみます。?

Answering よくえいがをみますか。(Genki I Workbook)

That is incorrect because you've made ときどき the object of みます.

いいえ、ときどきしかみません。

would be OK. いいえ、ときどきみます is a bit strange unless someone is asserting very
strongly that you watch films a lot.

You could answer with

> いいえ、[滅多]{めっ・た}にみません → No, I (only) seldom watch them.
