Thor 3, to me was boring and very textbook in terms of its action and story. Visually it was fun, but thats about it. The mix of childish and dry humour was a no for me.
Black Panther, with its poor cgi and lack of action (very noticeable) on 2nd viewings will age quite badly. Still a good movie though. Great writing and characters especially the ladies. In fact, Tessa was the highlight for Thor for me.
