Do you need multiple viewings to really determine if you like/dislike a movie or not?

Over the years, I have found that very often just one viewing of a film is not enough to make a full assessment of it. I was just curious if you folks also tend to give films more than one viewing to officially determine if you are "in" or "out"? I dont mean seeing it once a long time ago as a kid and then rewatching it as an adult. Thats a different scenario. I mean watching it twice fairly close together in time.

Here a few examples of movies where a second(or even third) viewing changed my stance considerably.

Blade Runner - I hated this the first time but slowly appreciated it more and more. It took about 4-5 viewings for it to finally get me.

No Country for Old Men - Second viewing was the best and I love it now.

Eyes Wide Shut - Second viewing did it for me.

Dracula - Second/third viewing really got me into it.

Now, some where a second viewing lowered my initial feelings:

Transformers 3 - The 45 minute battle scene at the end ruined it the second time around.

Full Metal Jacket - I just cant watch this anymore, likied it first time though.

Sunshine - Caught me by surprise the first time around but then I was like meh and sold it.
