I've mentioned before, but personally I'd much rather see more focus on animations than more movie clips. The clips should really bookend modes etc - little rewards for starting and completing things, but the moment to moment play needs great/varied animations and callouts. Couple of examples (using Avengers IQ, which I own and love but the animations are not the best). Look at the original open play screen for Avengers IQ (basically a static empty trophy room), it was terrible there was absolutely nothing going on as you were playing, and it made the game feel so empty. Compare any combo shot in Avengers IQ to something like the Ninjapocalypse shot in Deadpool, it's worlds apart.
Would be great to see similar things here - making a combo during open play (or a certain/specific combo) makes a bloody knife slash across the screen or I dunno, just something to give you some really satisfying feedback to shots.
Also - I actually love the way they've made the animations match the incredible artwork - so I really hope they continue to build on this. That's something I've wanted them to do with all the latest Sterns - to see some Zombie Yeti artwork animated on the LCD would be incredible.
EDIT: also wanted to mention that Hedge Multiball insert thing. It's minor, but once you notice it, it's hard to unsee - that should definitely be corrected.
