Would it be considered a spoiler if I said...

...I thought this was a totally average, silly, low-mental-impact, forgettable movie until the two twists showed up, and then my opinion of it changed dramatically?

I love movies that show that the people involved actually put some effort and imagination into it. I was about to post and say, "Hey, this movie actually has TWO imaginative, unexpected, intelligent twists!" but I didn't know if that would be construed as spoiling, or simply praising the movie and recommending that others actually take the 90 minutes out of their lives to watch it.

Thoughts?
