Is 「(i-adjective) + そうだったと思う」 grammatical/natural?


The lack of Google results for this kind of construction (relative to the
number for the equivalent [i-adjective] + そうだと思う and [i-adjective] + そうだと思った
for many i-adjectives) made me antsy about using it.

E.g. 「ジム・モリソンはすごく面白そうだったと思う」"I think Jim Morrison seems like he was really
interesting."

Am I doing something wrong here?




Yes it's natural and it means "I think he seemed very interesting". You are
thinking now, and you are thinking about the past situation regarding him.

You can use it when you are recalling your vague memory.

And you can also use it when you are implying the statement is no longer true
now.

> 過去には、ジム・モリソンはすごく面白そうだったと思う。今は誰も彼に興味はないけどね。
