Not even close, although I admit a bias for Strange as I read Dr Strange occasionally, when I was a kid.
Deadpool is action packed and hilarious, but really the only role Ryan Reynolds can pull off without being laughed off the screen. The fourth wall thing is amusing at first, but gets a bit old after a while.
The supporting cast were fun, but kind of stock.
I thought that Colossus was great, as was TNW - and of course I'll see almost any movie with Gina Carano in it.
But,they're both origin stories, and in that regard.....
....Dr Strange is the total package, a brilliant performance by the lead. The story is the classic hero's journey but done par excellence.
Visuals are literally out of this world, and there's humour, but it doesn't overshadow the rest of the film.
The supporting cast, particularly Swinton, is superb. (Overall, Strange has a much, much stronger cast).
Both films have slightly underwhelming villains, although Strange has a much, much, much more impressive final boss !
While I'd give Deadpool an 7/10, it was a good movie and entertaining but I kind of forgot about it afterwards - Dr Strange, I wanted to see it again right away definitely a 9/10 or better.
