this is really one of those movies that only works in theaters when a crowd laugh is infectious and you enjoy the vibes with the crowd. I liked the movie when I saw it opening weekend with a packed theater, all the cameos were a big highlight especially with the crowd reactions.
i re-watched the (really, really good) cam copy last night at home and yeah its pretty boring on rewatch for long stretches and not really a lot of humor compared to the first two. The first wolverine v dp fight is very cool especially the way wolverine moves, the opening logan sequence is ok but the music choice sucks, deadpool corps was cool but way too short and kind of a lame final fight. i was really bored for most of the movie, its definitely not a very rewatchable movie.
DP2 suffered the same problem too, big stretches of it are really boring but its humor is a bit more rapid fire, i'd say the weak link in that movie is making a kid your villain doesn't really work. DP3s problems are a bit more glaring, too many villains - should have focused just on cassandra and removed TVA/Paradox - and not enough jokes. DP3 rarely feels like its a sequel to DP1 & 2.
