The other Lego parts were better ...

So I see that. Have previously Lego Star Wars (Complete Saga), Harry Potter and now Batman 2 (DC ...) played.
Strangely, the part acts here as a step backwards in terms of gameplay, use and fun factor, so I had to look really more than once after the date of whether that so true.

Control:
Control is carried out as usual, but the flying of helicopters is cruel uncomfortable.
The control of the vehicles is buggy, because sometimes you can use R2 and L2, the next time again not.

"Camera work":
Without going into details ... it just does not go times GAR. The camera is often so bad positioned switches and lovingly designed items disappear behind any plates or level sections.
Lately there a dynamic split screen, so that the 2 players sometimes can remove from each other (one can also provide vertically). However, that has tens of disadvantages:
1. The Coop factor often gets lost a little
2. grappling hook, etc. can be partly no longer be used because the camera can zoom the crosshair only limited close to the split screen edge.
3. It jerky enormously in some levels (PS3 Slim) when a lot happening on the screen.

Gameplay & level design:
The puzzles are places blockers. That is to progress you have to traipse back again forever to get to one of the dozens of suits. The ending is that the other players just waiting. The levels are divided extremely confusing. In tiny sections there are extremely much Klickibunti and shades, so you keep track - especially with Batman in Black - MUST lose. In addition, one in the meantime in Gotham City is staying ... while it was fun in the other LEGO games rumzueiern times in Space cafe or to explore Hogwarts, there is here a torment because Gotham is so gigantic that a the Lust goes - especially at the poor orientation so that one even has a map on which you can set markers ...
Objects are so stupid placed that one hangs either turn over or jump. With a vehicle to land behind a guardrail is agonizing because you have miles herumdödeln to tens of trees to finally find the way to the street.

Bugs:
There is a 33% chance that the game * not * crashes before a cutscene. -.-

Remaining fun:
Well, LEGO halt. Bashing things and collect tens of stones. In addition, Superman and the Superman-Batman ratio entertaining.

Conclusion:
It seems as if art, level design and bug fixing have deteriorated compared to its predecessors. Too bad. Can of course still be fun.
